Regarding the MessageBox below the splash problem: splash at some point gains WS_EX_TOPMOST style set, that's not something that application does, it's a wineserver action.
wineserver does that in response to SetWindowPos(HWND_TOPMOST, splash), so apparently that's an application desire to make the splash top most.
It's not clear whether MessageBox code should cope with such situations, or WS_EX_TOPMOST should be removed at some point from splash.
Do you have Windows around to check with Spy++ or similar tool what styles MessageBox and splash windows have there?
