I should further note that much of the time I am ssh'ed into one of several different Linux
machines, so in that case, I would be running less from the Linux machine and displaying in the
Cygwin xterm.

Hmmm, so now I'm starting to think the combination I have trouble with is an older less on a Linux
machine and Cygwin xterm. I don't control what is installed on some of these Linux machines. Do you
know if there were known issues with less, for example, the following is one that has significant
issues:

[appldev3 AT ebs-app-dev3 HAF]$ less --version
less 458 (POSIX regular expressions)
