Sometimes icq turns on when I launch my program. Is this a lost device same as if I tabbed out? Also sometimes I launch a small window but I'm doing a few things at once and then my program does not respond to mouse clicks but everything else works fine. What was lost this time?

Yes. A lost device is the result of the window losing focus, whether it be through minimizing it, alt-tabbing, popups, or just clicking on another window.

Are you using DirectInput? Have you Re-aquired your devices?

All I do to use mouse and keyboard is:

IDirectInputDevice8Object->Acquire();

And then I read.

Do I need to Reset anything like when I lose the device?

example:

D3DERR_DEVICELOST==IDirect3DDevice8Object->TestCooperativeLevel();

if(D3DERR_DEVICENOTRESET==IDirect3DDevice8Object->TestCooperativeLevel())
{
IDirect3DDevice8Object->Reset();
}

Any resources like Buffers and Textures that you created without using the Managed Pool need to be released before reset and recreated after reset. The easiest way to solve this problem is just to put almost everything into the Managed pool, at least Microsoft claims that the managed pool is sufficient for most resources.

You can lose DirectInput devices just like Direct3D ones. You need to check for their loss and reaquire them when you can get access to them again.
