A new messege for you, Yukata.
I found tonight that when gciba 2.0 is running(on Win7), Visual Studio 2005 SP1 IDE(run as Admin) becomes completely irresponsive for Ctrl+Tab. Normally VS2005 will respond to Ctrl+Tab and cycle through the list of opened source files.
But in my office Windows XP SP2, gciba 2.0 does not affected VS2005 SP1 IDE’s Ctrl+Tab behavior.
So, it is still weird.
