1451: 1786:... Our detailed analysis of the EoP exploit revealed that the vulnerability it used belongs to the win32k.sys driver ... The vulnerability itself is related to windows switching functionality (for example, the one triggered using the Alt-Tab key combination). That's why the exploit's code uses a few WinAPI calls (GetKeyState/SetKeyState) to emulate a key press operation. ... 1219: 36: 1123:

After restarting sidebar the problem appears again. This bug also happens when ipoint.exe, the Microsoft Intellipoint mouse driver, is running. Other programs causing this behaviour were reported as well.
