First like to say this is a great app! I had the same problem as spirytsick, but a reboot seemed to help. I am running the app on an N800, and the app crashed after I had locked the screen and then subsequently unlocked the screen. The screen when white and when the desktop came back, the new applet was gone and the old sound and brightness applets returned, even though I had shut them off.
Also, just a question regarding the question of minimizing the applet by clicking to the desktop. I notice that your applet does not have the same border as the other applets. Does have anything to do with the desktop click detection? Anyway, just thought I'd mention it if it might help.
