Every time I reboot from Boot Camp into OS X, the bootloader gets to the login screen, and then after I've entered my username and password, the screen will just go grey. I have to force a restart with the power button, and then when I reboot, it proceeds normally.

Specifics: Windows 7 Professional 32-bit in Boot Camp, and OS X 10.7.1. The same issue happened with 10.7.0. This is on a late-2008 MacBook Pro 15".

do you have Sophos Antivirus installed? –  Stu Wilson Mar 21 '12 at 20:53
Is this still and issue? If so, what version of OS X are you running now? –  Nate Bird Mar 23 '12 at 18:07
Not happened for some time now, don't know what actually fixed it. I'm now on 10.7.3, and yes i do have sophos installed –  Doozer1979 Mar 24 '12 at 15:59
