I disabled IntelliSence for c++

and when I save any file

the cpu usage of devenv.exe must be 100%(25% for my 4-core laptop)

with spy++'s help we can see a bug loop of WM_WINDOWPOSCHANGING

I think this is a very big big problem that it causes my cpu fan working madly!

bug on

win7 + vs2012

win8 + vs2012 whth update1
