Is this an error that is thrown by just the launcher itself or are you using a 
theme on top of the launcher?

thrown by just the launcher itself,but I think this problem maybe related with 
the build environment

I have the same problem. It seems to be on all buttons that use the 
android:onClick event. Also have it on apply theme and get themes buttons in 
ADWsettings 
Is it a build environment problem?
Porting CM7 with ADWLauncher to archos gen7 (A5IT) and gen8 (A101IT, A70IT etc)
