found a bug, please check if this happens to you too:
open the gallery app, browse through pictures for some time - press HOME - lock screen. after some time you will find gallery using 60-80% cpu (samsung task manager widget turns red).
killing with task manager does the job, so does exiting Gallery with BACK button, i cannot reproduce the problem in any other case but going directly home.
thanks for any feedback!
hands down to Faryaab for this is truly amazing rom!
