It takes quite a while for this to show up. Task Manager says that 
explorer.exe holds 9,999 GDI objects when it does and each menu access 
adds 4 to that figure (before it hits the roof).

I believe start-process may work as expected, but the program that was 
started does not. Maybe there is some error code from CreateProcess 
indicating this but I do not know. The started program is not painted on 
the screen as it should. Just a transparent window with borders.

I think I have found the circumstances then this bug shows up. This bug 
only shows up if you use StickyKeys. (I am rather used to notice obscure 
bugs and this is one of them. MS has even once told my employer that 
they wanted me to stop reporting bugs. Until things finally broke down 
completely because of the bugs I noticed subtle things from.)

So now I am thinking about helping MS by reporting the bug. There 
something inside me hesitating, but I think I will still do that. ;-)

Do you have any idea of where to report it?
