32 was very unstable when 2.2 first came out, but maybe this was fixed? I was hoping it would fix my launcher FC from folders/themes(I think from these?), but it has definitely not helped with the Launcher.
Eitherway, there is an easy way to fix it.
Open a terminal app, type su, then, a2sd largeheap (largeheap is 1 word) It will set you to 24. a2sd help for the commands to get back to 32 (megaheap I believe)
