#7 Icon often gets "stuck" in Windows 7

[Tao Yue]

In Windows 7 (64-bit), the icon often gets "stuck" when you switch out of a program, change to another text service, and then switch back into the program.

Pinyinput continues to work correctly, but the icon will show MS Pinyin, or vice versa.

Not sure if this can be fixed in Pinyinput, or if it's just an issue with the compatibility layer for IME. When coding up my TSF text service, I found that it behaved in the exact opposite way -- the icon worked fine on Vista and 7, but got stuck on XP. With Pinyinput, the icon works fine on XP, but gets stuck on 7.
