Subject: Startx crashes while program running in xterm window
Reply-to: cygwin-xfree at cygwin dot com

Hi:

Startx crashes while program running in xterm window.

Circumstances of crash:
- Running xstart in a cygwin command window
- Running homemade program GrafxDemo in the xterm window launched by startx
- While GrafxDemo is running, crash occurs: xterm window closed, startx ends.

See below Startx dialog and XWin.log file.

Thank you,
D. Oublon
