Thanks for starting the threadRaynne!
So far, Pocket Controller Pro will not work when its DLL files are moved to SD Card. Looks like its pretty picky

I moved its dll files back & it wrks fine.
So far, this is the only app that I've had an issue with.
I saved about 2.7 MB by moving dlls to SD. Thanks DinarSoft

Will list any others that bark after being moved
Edit: Add ZenoKeyboard to the list. I'm not able to use it. I moved the dll file back to MM, and it still won't stick as my input choice. Now, I did delete the registry files via SKTools, but I did back them up. My hunch is that once I restore the deleted registry entry, it should work again.
