An edge case. I run Windows 7, 64-bit, with the Blackbox for Windows
shell. It works for me, and I like it, and I'll keep using it as long as I can. Blackbox doesn't look right with Aero enabled, and so I disable it most of the time. With Aero, goes VSync and sometimes graphics acceleration for things like movies and some games. That means tearing.
Right now, if I don't want that tearing, I go to the Personalization area of the Control Panel, and pick an Aero theme (Windows 7, Architecture, Characters, etc.), which makes Blackbox look crappy, but temporarily lets my full-screen application look its best. Then I flip it back when done.
I'd like a quick toggle that allows me to switch between an Aero theme and a non-Aero theme, so I can have my cake and eat it too.
How would this look? Maybe a small window with two buttons, each indicating a theme, and a config dialog. If possible, something that invisibly switches between two pre-selected themes, kills itself, and requires no additional input of any kind.
