Yep...just completed the full OS install and my Mod wheels are back working again.

Strange one but hey... at least it's working.

Noticed 1 problem with the OS update so far. There seems to be a problem switching between GM Instruments and GM Drum kits.

The keyboard does not change always between them. You might for example load a drum kit and hear it, then try go back to a Piano and you still have a drum kit.
