[R-SIG-Mac] Quartz copy/paste bug?

I have encountered this bug occasionally, but very rarely. The  
problem is, I didn't figure a way to reproduce it consistently. I was  
fiddling around with Quartz locking etc., but without reproducible  
example, it's almost impossible to fix. If you or anyone else could  
come up with a way to reproduce this behavior consistently, it would  
be great. Please let me know if you have a way for this to appear  
more often - I'd appreciate that.
