I recently upgraded from a fairly ancient Tiger OSX to the latest
Snow Leopard (10.6.2).
I've got most of the teething problems settled, but there is one
really annoying phenomenon that I cannot fathom.
When I open an X11 window for R graphics, it will ***sometimes***
refuse to let me move the pointer over the window!!! I.e. if I
move the pointer over the window, the window jumps to another
part of the screen. If I chase it there, it jumps again. This
precludes raising or moving the window.
The problem is that this is an intermittent fault. Sometimes it
will happen, and sometimes it won't. (Once it starts happening,
it won't quit, however.) Makes it very hard to diagnose
or trace the fault.
Has anybody else ever encountered anything like this? Has anyone
any idea what's causing this phenomenon, or how I could trace it
down and rectify the problem?
Grateful for any suggestions.
cheers,
Rolf Turner
P. S. I start R from the command line in a terminal window; I don't
use the R GUI.
