Uhm, well, you know, 2 is more than 1. I *think* nano crashed once in 
the past 10 years or so. Seriously, I cannot remember any crashes 
since 2.6 or 2.7 (when I started compiling them myself) which were not 
caused by other circumstances. I do remember issues with syntax 
highlighting but I think this was with older versions.

Attached.

That's good advice. I will do this. Thanks a lot!
