John, To the best of my knowledge this problem in R.app has been around at least since the R-2.8 days, but likely much longer. I never use R from a Terminal, so don't know if it occurs or not outside R.app.
It's not related to Rcmdr and you're observation is indeed one of the better ways to kind of reproduce the issue. Not sure if it always does though. If you have a 'hard' way of crashing R.app, please let me know the sequence. In cases when no output is written to the console of R.app I tend to make sure I enter an empty line before closing the graphics window. This issue and sometimes very long sequences of plots (never have been able to make that reproducible, sometimes the crash happens up to a minute after R finishes a series of plots and I'm working in an external editor like TextMate) are hard to pin down. Regards, Rob Note: Hope you don't mind I've removed the R-bugs & R-devel Cc's.
