However, if I run mintty from my xterm window I have some problems.
For example, say I have open xterm (from startxwin.csh) with
xterm +tb -j -sb -geometry 80x84-6+0 &
this sets LINES set to 84.
If I have set up .minttyrc with
Rows=100
then after I go to my mintty window and back to my xterm, my xterm window
is messed up, e.g., top rows under `less` are off the screen.
There is no such problem, when running xterm, if I open an additional
mintty window as a Windows shortcut since it seems to open independently
-- without taking on the environment variables in my xterm window.
