After upgrading to Xfree86-xserv to 4.3.0-47 using the cygwin setup, GNU emacs crashes with the following messages:
X protocol error: BadWindow (invalid Window parameter) on protocol request 38 The crash occurs as soon as the mouse is moved *after* the RMB is pressed down. It is systematic and can be repeated easily The crash occurs with both emacs 21.2.1 and 21.3.1. The OS is Red Hat 9. The problem does not sem to occur with other X applications on the same tunnel. xemacs works fine. Surprisingly enough, the crash does not occur all the time. Within the same session, emacs sometimes works just fine. When that is the case, it works fine repeatedly. The crash if frequent though to prevent any reliable use of emacs, and once it kicks in it is systematic. The conditions that trigger the problem are unclear. Stopping and restarting the X server does not help. The problem does not seem to exist in 4.3.0-44, so downgrading to that version seems to be a valid workaround. -erik
