The CM option is going to have more sway with the OS than the LauncherPro option (since it is the CM option is from the OS itself vs an app telling the OS to not kill itself).
I've also had even better success with screen redraws using this method. I think it's what the CM toggle is supposed to do, but this actually does it.
1) MAKE A NANDROID BACKUP
In your terminal application on your phone (if you have to ask what this is, Google it, download it from the market)
su (enter) echo ro.HOME_APP_ADJ=1 >> /data/local.prop (enter) reboot (enter)
If you want to undo what this command does, simply remove that toggle from: /data/local.prop, or if you did not have this file (like I did not) prior to the mod...remove it entirely
