[R-SIG-Mac] Wandering X11 windows under Snow Leopard.

[Don MacQueen]

The only suggestion I have, and it's a weak one, would be to try 
starting R from the command line in an xterm window, instead of 
Terminal, and see if it's stable there.

I've used R just a little bit on a Snow Leopard machine and have not 
experienced what you describe -- but I do work entirely within X11, 
not in what I would call a hybrid environment of Terminal plus X 
windows.
