Posting on MM6 site as advised by Bones

currently playing another run through of MM7. have encountered a problem which I have not come across before. When I load any of my save games and cast the fly spell I immediately fly up to the max. I cant move forward of backward. can rotate left or right. have tried sleeping and recasting the fly spell to no avail I have also uninstalled and reinstalled also to no avail.

Any one else come across this problem?
