Something happened, I don't know what. Aero doesn't work in my themes anymore. It did to begin with, in both Stable 4 and Alpha 5, and it works just fine on my desktop, but now even when I uninstall and reinstall, themes that have aero enabled have a blue frame.
PLEASE, someone let me know if there's a fix?
I'm guessing it's some setting that got messed up, but when I uninstalled, I deleted my settings in AppData/Local and in Program Files, so I don't know what else would be screwing with it.
