X11R7.4 and Webex problem, X apps hang

Hello,
Just wanted to mention a bug I've seen with Cygwin, X11R7.4, and Webex
(a Java based meeting and collaboration tool, www.webex.com). Webex
has the ability to share a users desktop or individual applications
with other people logged into the meeting.
I can run X11 apps from Cygwin nicely, but if I try to run a Webex
"share application" session, it will cause the X11 apps to hang. I've
been able to use Webex and Cygwin/X prior to X11R7.4.
Unfortunately, there is no information in the X11 logfiles. Also,
Webex is a closed source Java program, so I have no control over it.
As a test, I tried running a few Cygwin X apps, but using Xwin32
instead of Cygwin's X server (under Windows 2000). This didn't crash
with Webex, which indicates there is some problem between Cygwin's X
and Webex's share application feature. Cygwin is at version 1.5.25-15
(updated a couple weeks ago), xorg-server is at 1.5.3-7, and cygcheck
doesn't show any problems.
Sorry in advance for the vague bug report, but its a difficult problem
to debug. I've suggested our company switch from Webex to a different
product (one that also works under Linux), but they prefer to use
Webex and have asked that I submit this as a bug report.
Cheers,
Chris LeBlanc
