Sorry about that: my employer forces me to use Lotus Notes.  I think I 
turned off
HTML, but you never know with Notes.  If this message doesn't work, I'll 
switch
to my ISP account.

I submitted the disclaimer request to my local general manager, who 
immediately
said isn't "RedHat a competitor?"  So we'll see what happens :-)

I've seen it, it's one of the things I want to fix.  The Windows console 
api
is screwy in this area, it normally doesn't give events for windows 
resize- only
buffer resize.  I'm not sure how Cygwin is dealing with this yet.  I'm 
guessing it
polls, but I haven't looked into it enough yet.

I want it to work like an xterm: so unless the application enables mouse 
support,
the simple left button to select, middle button to paste thing should
work as in xterm- but of course everything should be optional.  I'm not 
yet sure
how this should interact with windows clipboard.
