After receiving some updates via the update manager yesterday I've had an issue. One update was for the newest version of Gimp 2.8 I think. Since this update, Gimp is freezing after 2 layers. Can I undo, or return to my previous version? I'm unsure what to do.

Ubuntu 12.04
Compaq Presario R3000
1.2 GIG Ram
AMD Athlon 64 Processor 3000+
32 bit OS

The bot is old as heck, but it has runs great! Used mainly for Inkscape and Gimp only... some surfing. Everything else is working as per normal.

Thank you very much in advance!
