Partial +relay log

This bug applies to Su Doku Active by Greenstreet Games. Unfortunately I don't
think there is a freely-downloadable version of this game.

When running in virtual desktop mode, the window title text flickers as the
mouse is moved. There is no flickering in Windows XP.

The game requires MFC42.DLL, so it could be some call to that which is calling
SetWindowTextA repeatedly as the mouse is moved. It may be that Windows checks
the title text being set, and optimises out the rendering if the text is the
same as the existing title.

Attached is an extract from a WINEDEBUG=+relay log which shows several calls to
SetWindowTextA.
