Apps and windows keep closing HELP!

[alarm]

Hello
I have a tablet on ICS which keeps closing apps and menus and returning to the homescreen.
Is this a bug or is it likely that the tablet is faulty?
Thanks in advance for any help.

Your tab just upgraded to ICS or it already ICS since you bought it?

- Try to uninstall and reinstall that apps
- Have you try factory data reset?
