Xemacs/cygwin hangs using mouse wheel

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! Occasionally, xemacs/cygwin hangs when using the mouse wheel. It's not clear when this happens, but it seems to be more often when flyspell is active. On my machine I can always reproduce as follows: - Start xemacs -no-init-file -vanilla - Load a largish text file - Start juggling quickly back & forth with the mouse wheel, scrolling the document backwards/forwards - Within a few seconds xemacs hangs. Sometimes CPU usage goes to 100% but this is not consistent Btw, this was also a problem with 21.4.3 rgds Jeppe ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-5.0 TSUNAMI 1.3.2(0.39/3/2) 2001-05-20 23:28 i686 unknown ./configure '--with-dragndrop' '--with-postgresql=no' '--with-x=no' '--bindir=/usr/local/bin/i686-pc-cygwin' '--with-site-lisp=yes' '--with-ipv6-cname=no' '--with-netinstall' XEmacs 21.4.5 "Civil Service (Windows)" configured for `i686-pc-cygwin'.
