Also, let me report that I had to install, and reinstall WB 3 times to get it to work after uninstalling everything with Impulse. Impulse didn't correctly uninstall it either, I had to uninstall WB via add/remove too.
I would advise that those who are uninstalling Impulse to uninstall WindowBlinds first. Uninstalling MyColors and SKS first makes Impulse take WB out of the list of installed apps.
