Does the cursor appear to stick to objects?
Try setting the ROLLOVERTIPS (System Variable) to 0 to shut them off.
I added a macro to toggle them Off/On:
Command Name Rollover Tooltips
Description Rollover Tooltips toggle
Macro ^P(ai_onoff "rollovertips") ^P
After adding it to the ribbon add the display name: $(if,$(getvar,rollovertips),!.)Rollover Tooltips
Then it will display highlighted when toggled on.
