Div ao passar o mouse no campo não funciona

Eu tenho esta função, que funcionava bem pra mim, agora não sei por qual motivo não funciona, acho que estou esquecendo de algum detalhe.
Este é o css:

 #mostrar {
    display: none;

#CodigoCobrancaID:not(:placeholder-shown):hover + #mostrar {
    display: block;

.div_teste {
    width: 350px;
    height: 120px;
    background: #ffffff;
    position: absolute;
    z-index: 100;
    top: 30%;
    left: 40%;
    border: 1px solid;


Eu preciso que ao passar o mouse no campo e ele estiver preenchido, aparecer a div, porém não está aparecendo, de nenhuma forma, isso funcionava bem pra mim, mas agora parou.

multiple mouse events for splitted screen on Libgdx

well i am working in a fps game , and i also splitted the screen in two parts for two players , i am using the mouseMoved event for the camera,, but in this situation literally i need two cameras each one with their own mouseMOved event ,

//here is the code to manipulate the camera with the mouse
public boolean mouseMoved(int screenX, int screenY) {


     float x = mouseX -screenX;

     float y = mouseY -screenY;
     cam.direction.y +=   Math.sin( y/180f) ;
     cam2.direction.y +=   Math.sin( y/180f) ;

     mouseX = screenX;
     mouseY = screenY;


    return false;

here you can see how the game looks

here is the splitted screen , but the mouseMOved event keep affecting the two cameras , i want a moseMoved for each one! is this posible ?

Keyboard and mouse not working in Windows 2003 Server / HPML350 G5 server?

I have currently commenced working at a new company which is using Windows Server 2003. I am able to remote desktop into the server and it all works fine. The only problem is if I go to the server room and try to login into the Terminal server via the keyboard and mouse they do not work (so the actual mouse physically connected to the server).

When I reboot the server the keyboard works fine in the HP Bios setup, and if I press F8 to get to the Windows pre-boot options, the keyboard works fine!

It’s only as soon as Windows 2003 starts up and you get to the login screen, there is no mouse or keyboard working.

I have checked the device manager and the kb and mouse are returning a code 10 error, could not start.

What i have tried:

  • Uninstall / reinstall keyboard/mouse
  • disable / re-enable
  • countless reboots.

@Anon: thanks for the tips. And you’re right. nothing is ever a silly suggestion. The startup folder is empty. Are you also referring to msconfig? hang on… good point… i just checked msconfig and looked under services. I have noticed the Human Interface Device Access is stopped and not running. I went to services.msc and tried running the services and now have received the following error

Could not start HIDA service on local comp – Error 2: The system cannot find the specified file

As for IRQ conflicts there is no mention of any in the device manager. I have been in the BIOS setup many times and IRQ selections are very very limited to 3,5,10,11 I believe for the devices and ports etc. I don’t believe the IRQ is the case on this one. Can you assist on what might be the cause for this error 2? I got a feeling the Windows 2003 is missing some files or possibly corrupted driver?

Question: My mouse cursor drifts to the left?

so this is going to be weird to explain right.

i have a logitech g502. if i center my cursor on my monitor, and center the mouse on my mouse pad, and then spin my mouse in a bunch of circles, the mouse stays in the center of the mousepad, but the cursor starts to drift to the left side of the monitor. So after a few seconds, the cursor will hit the edge of the monitor, while the mouse is still in the center of the mousepad. Any ideas whats causing this?

ive tested 2 mousepads, not the issue, it happens on both my 1080p and 2k monitor. and happens on multiple DPIs

How do I share two monitors, one mouse, and one keyboard between one Mac and two PCs?

I have the following machines that I would like to share two monitors:

  • A Macbook Pro with two thunderbolt display ports
  • A Windows PC for work with one HDMI and one VGA port
  • A Windows gaming PC with two DVI ports

Each of my monitors have 1 DVI port, and 1 VGA port. Am willing to buy new ones since they need to be upgraded anyway.

What option do I have to share both monitors + keyboard + mouse between all three computers?

Microsoft Comfort Optical Mouse 3000 back-button

Is there a process / command that can configure the back-button of MS mouse? The other controls of the mouse function properly.

I tried this process but was not successful


xinput set-button-map “Microsoft Microsoft Optical Mouse with Tilt
Wheel” 1 2 3 4 5 6 9 7 8

unable to find device ‘Microsoft Microsoft Optical Mouse with Tilt Wheel’


This command requires that the mouse be plugged in via USB and not PS2 adapter. The functionality works, however, if the mouse is unpluged and plugged in again the command has to be issued again.

Any suggestions to make the setting “stick”, would be appreciated.

Mouse scroll in VLC fast forward and increase volume in the same time

I encounter a weird issue with recent VLC version and I am not able to find information about this problem.

When I scroll using the mouse wheel during a video, it fast forward the video and increase the volume in the same time it (reciprocally rewind and decrease volume).

Before < some update > the scroll simply decreased and increased volume.

When I go in Preferences > Hotkeys there no mention of mouse wheel.

I am probably missing something obvious but anyone know where I can find the option to correct this problem ?

Will Blizzard ban you for using a macro mouse?

Someone I know just picked up a gaming mouse with the ability to set macros that will send timed keystrokes into WoW. Is this a bannable offense?

To be clear, these are not using WoW’s macro system; they are essentially timing scripts that will replay a specific set of button presses with the intent of setting up a kill sequence of perfectly timed spell casts with the press of one button.
