Tooltips in own windows

[Duane Clark]

I just wanted to make sure folks were aware of a tooltip regression, 
since I don't think I have seen mention of it here. It is easily seen in 
any Control Spy, but effects other apps (though not all, curiously). It 
manifests itself as a complete window border around tooltips. I have not 
tracked down where the regression occured, but could do so if no one 
else was looking at this.
