I noticed that sometimes when I hit F2 to enter bios as the computer is booting up my mouse would be locked up (frozen in center of screen) after getting into bios. Keyboard always worked fine. After awhile I began to realize that this only happens when I do a Windows restart to get into bios instead of shutting the machine off first. If I shutdown first (or after doing a CTL-ALT-DEL while in bios after experiencing a frozen mouse), the mouse is detected and works fine when I then enter bios. I tried the mouse on both black USB2 ports and both have the same effect. Anyone know if this bug is being addressed?
My configuration:
Intel DZ77RE-75K (bios 53)
Intel 3770K
16GB ram (2 x 8GB dual channel)
Windows 7 Ultimate 64bit
HDMI to DVI into monitor at 1920x1200 @ 59hz
USB Microsoft optical wheel mouse
PS/2 Microsoft keyboard
