Probably you know the Visual Assist plug-in for Microsoft Visual Studio, which makes C++ programming in the environment zillion times handier. The story is about the bootstrap tip that highlights the feature of restoring files. While the tip window is shown, there is a second dialog box painted in the window. Since it is centred w.r.t. the screen, you perceive it as a real dialog box. Moreover, it is the usual case when Visual Assist suggests you to load some files from backup while MSVS is loading, because it does not always shut down properly. Thus, you try to close it clicking Yes or No, but nothing happens! The box is still in its place! That was really annoying.
