So first off, I'm loving CM 6. The only thing that bugs me a little are the redraws that occur here and there.
Locking home in memory through CM settings doesn't work that well. And checking the 'system persistent' option in the ADW settings does work, but when its checked, the screen stops rotating even when i slide it open to use the keyboard, which is kind of a problem when i try to reply to texts popups using handcent. I changed the VM heap size to 32M and redraws still happen.
