[Android Apps and Games] linuxjacques:
I tried GMD HideBar (with and without busybox checked) and the 2.5.0 version of GestureControl but they both still crash the GUI.

It looks like once the status bar is hidden (it does hide for me BTW) something times out (about 40 seconds later) in the ActivityManager process causing a crash.

The logcats are very long but I think these are the relevant parts:

BTW, I tried the http://ppareit.github.com/HideBar/ app but it doesn't even hide the bar in my case (gtab 7.0 plus ICS).

I also tried Nova Launcher but no difference (well the crash seemed to move to 50 seconds but that could be a fluke).
