I've gone back and forth between cm7 and stock several times over the last few days for various reasons.
Now each time I have flashed back to cm7 I have noticed pieces missing.
I get the right splash and boot screens but when i got to the lock screen I had the new wallpaper but the old slider.
On homescreen I had cm7 wallpaper but different icons in the pulldown bar, cm7 icons on system apps, but stock icons for phone, text and contacts.
This last time I got my old wallpaper, dock, and all but 5 system icons are stock.

My cm7 seems to have pieces falling off of it like a rotting zombie!

It seems to be working ok so I'm rolling with it for now, but what could be causing this?

I checked my info and it says I do have cm7 and everything so I know it's installed. And I tried reclicking themes in the launcher but nothing changed.
