IssueTracker

I also have the same issue so it seems to be a real problem.

Dup here:

http://code.google.com/p/android/issues/detail?id=27959&can=1&q=fixed%20position&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

Though it's a bit more detailed with the minimum necessary to reproduce.

why is this marked has Obsolete? this is still a bug that is happening and its difficult to fix.
for all who are looking for a solution use this:
