Hi Steve, thanks for your reply - I'm running OS X El Capitan version 10.11.6 - i'll try restoring the settings now, cheers Michael
Unfortunately no joy - just reset - started working and same issue - random spinning wheel
How does the scroll wheel work in other applications?
I think Michael is referring to the animated wait icon, Steve.
Does your InDesign has GPU enabled ?
