Thanks.  Unfortunately, I cannot reproduce this on my machine (which
runs MS-Windows).

How many times do you need to move the mouse back and forth before it
crashes?  Does it always crash after the same number of
selections/deselections?  How do you "deselect" the text, exactly?

If you can consistently reproduce the crash with the recipe you
posted, then please type "pr *bidi_it" in frame #1 and post the
results here.

Thanks.
