Michael,

Your problem is probably related  to the problem I have with RR on OS 
X. See "Trouble with graphics display in OS X" in the list archives. 
Or check out

go url "http://home.infostations.net/jhurley/DisplayProblems.rev"

RR does not do a screen refresh after a "set the loc of ...." in OS X 
and so an "Unlock screen" command is required. This slows the OS X 
performance.
