Try to lock the launcher in memory.
That's a memory issue. Maybe you have many Widgets and live wallpaper (and maybe many apps open), which consumes a lot of ram.
Also if you have wake lock, uninstall it.
Next version will maybe have the theme system.
Actually it is easier than I thought.
How do you lock the launcher in memory. Is it the same as on my EVO, adding a setting to build.prop?
Themes?!?! Cool!
Thanks,
