Would it be possible for you to also add some code for diagnosing problems with processes started from .startxwinrc?  I'm hoping it might help with the problem I reported in

  http://cygwin.com/ml/cygwin-xfree/2012-04/msg00050.html

BTW, I tried the snapshot at

  ftp://cygwin.com/pub/cygwinx/XWin.20120423-git-638383315ef51e46.exe.bz2

and the resulting log has a lot of messages like this:

 winMultiWindowXMsgProcErrorHandler - ERROR: BadWindow (invalid Window parameter)
 winMultiWindowXMsgProcErrorHandler - ERROR: BadMatch (invalid parameter attributes)

Is that to be expected, or does it indicate a real problem?
