This was R started in what way? Console? Terminal? An xterm shell running under X11?
Command-Tab switches between applications Command-` switches between windows within an application The following applies to R started in a Terminal window. You have two applications, Terminal, and X11 (though for me it's a Quartz window, not an X11 window). After dev.new(), X11 has two windows, Terminal has one window. When you use Command-Tab to switch back to "X11" you get whichever X11 window is active, namely the second one. Then use Command-` to get to the original graphics window. That's what I think is probably going on. -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 4/6/12 8:19 AM, "Bw Coder" <highbwco...@yahoo.com> wrote: >Hi, >This has been cross-posted on http://stackoverflow.com/q/10045109 > >While plotting to a window in R, X11 kept hanging.
