annoying folder bug

Attachment 53112Attachment 53113Hey all new to this forum so sorry if this has already been brought up.
I noticed the last few days when i press the back or home screen button my phone returns to the main screen with a folder open in the screen.
Its a folder i have put there with all my games in but its really bugging me that its opening itself. The only fix so far is to restart the phone but i shoudnt have to do this more than once a day. It is only one folder. I have 3 folders on my home screen and only the games one opens.
Any help would be much appreciated people may not be experiencing this as it has just randomly started doing it.

Phone is a samsung galaxy s3 on ics no root
Thanks in advance

my phone has the exact problem. s3.

Does anyone have a fix for this?.. I hope the jelly bean update fixes this problem!
