I don't remember seeing this on gtk2 with metacity either, but I
remember seeing this on WinXP. And on Delphi it's always been present,
up to Delphi2007. As the LCL, Delphi had code to store and restore
z-order on ShowModal, but it's easy to break the code using native
calls (maybe even without this)...
