I get the same error as roger, only it happens every time I log into XP x64 SP2.

"System settings protector has encountered a problem and needs to close.
Error signature
AppName: teatimer.exe AppVer: 1.6.1.22 ModName: kernel32.dll
ModVer: 5.2.3790.4062 Offset: 00022366"

I close that dialog and get another:

"Application Error
Exception EOutOfResources in module TeaTimer.exe at 000468FC.
Cannot create shell notification icon."

Then explorer.exe hangs. So I kill it and run explorer.exe and teatimer.exe again then everything is happy.

Issue does not occur on another partition where XP x86 SP3 lives a nice, quiet life with his wife and two children. Passersby were amazed by the unusually large amounts of blood. There were no survivors.
