xtrs 4.9 hanging in cygwin-xfree

[Damien Cymbal]

Hello,

I am trying to run xtrs 4.9 (http://www.tim-mann.org/xtrs.html) on the
latest (as of March 4) cygwin/XFree86 distribution.

xtrs launches and presents its initial display but then seems to hang (no
response to keyboard input, etc.)  xtrs on Linux is running without
problems.

I know nothing about X application development, but I have built xtrs in
debug mode and can fumble my way through gdb if somebody would through me a
few pointers of where I can get more pertinent info to help resolve this.

Thanks.
