Go into the Options dialog and "Helpers" tab. Set the timer to a high value and you should not see it again. PS> You might find you want to use different shortcuts than RMB anyhow. I never use RMB for view manips. Hover over the view commands to see the most recommended shortcut. Like I use Shift MMB for pan and in ST4 scroll wheel does zoom full time, so I find I need little else than this. if you need Window Area, its ALT MMB.
