I've been using Screen for over a decade, and I love this program, very solid.
Only in recent months have I started using the Multi display mode (flag -x). I
have started experiencing very occasional crashes since starting to use Multi
display mode- maybe once per month.
I need your help to help you discover the problem. I'm very inexperienced with
debugging tools. Perhaps I should be running strace with Screen and keeping a
log, or perhaps there is a debug version of Screen I could be using? I don't
know.
Please tell me what I need to do, so that upon next crash I can give you
complete information which reveals the reason for crash.
