That would be "top left quadrant"....oops.
To the best of my knowledge, there is no native option in Windows to enable this behavior.
Does this mean that if you "unload WB > use Display Properties\Themes tab\Theme drop-down list" to apply the Windows XP theme that you see this behavior? Or is it only when WB is loaded?
If WB still does not see the skins, I would venture to say this is part of the problem. It is my understanding that Stardock will attempt to release a new beta version sometime today 11/15, so you may want to restore Windows to the default theme > save skin folders > unistall / reboot / reinstall both WB and SS.
I was referring to just the native "themes" engine and applying "Luna" to make sure WB is unloaded and see if the issue persists. Sounds like you already know it is somewhere in the WB application procedure - which makes sense.
