Possible bug trying to run Eclipse GTK?

[<seterajunk at charter dot net>]

Hello,

I'm trying to run Eclipse M8 GTK version via the multiwindow mode.  I have no trouble running it in full desktop mode using XDMCP, but when I try to run just Eclipse (via an xterm) using either multiwindow or rootless mode, the application crashes.  Strangely, it seems to be fine until I move the cursor over the window and then it crashes.  Is this a Cygwin Xfree bug or an Eclipse bug or something else altogether?

Here is the error I get:
The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 63899 error_code 3 request_code 38 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will recieve the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior.  You can then get a meaninful
   backtrace from your debugger if you break on the gdk_x_error() function.)
   

Thanks,
Craig
