Default [Q] Home Switcher Crashes

I used Autonooter 3.0 and have been pretty happy. Home Switcher was working fine, until a couple of weeks ago. I only use it to switch to the stock launcher, so I can choose a new wallpaper and have it sized correctly. But when I start it now, the Home Switcher screen flashes for a second, and then it closes. I've tried uninstalling and reinstalling. No luck.

Any ideas?

Thanks, Lori
