R.app Editor

I need your help. I am writing code in the editor window for R.app,  
but when I write something like a^ (not sure of the correct technical  
term) the application hangs, and I can't write anymore. It's happening  
only with the symbol ^

Thanks,

Angel

I have seen this, at least on occasion, but only when
the circumflex is typed on the last line of the editor window.
I can't give a reprodicible example because as I indicated,
it seems to be an intermittent problem, so will be much
more difficult to track down.  My solution has been to
save the file, close the window and re-open the file.
Hitting ESC has unfrozen the window, but with the
loss of the cursor, which is disorienting so the save/reopen
strategy seems better.  It doesn't happen very often so
given there is a simple recovery strategy, I'm not bothered
by a quirk in an otherwise very handy editor.  Typing extra blank lines
at the end of the file seems to help, too.  I can't say whether
that is superstition, however.
