I have a few additional comments on the bug report I submitted on Tuesday about XEmacs hanging when trying to access the customize menus. 1) The problem can be reproduced with -vanilla. 2) The hang occurs with the last message "Loading build" 3) I'd be curious to know if any other Cygwin users can demonstrate the problem. 4) This would be minor with easy workarounds except that there is a serious side effect. Once XEmacs is hung the only way to kill it is with the Windows Task Manager. After killing XEmacs with the pulldown menus still displayed, menus are displayed incorrectly in XEmacs when it is restarted and in other applications as well. The menu background is sometimes black except right around the text and sometimes it is transparent. The only way I have been able to clear up the problem is to restart the system. 5) There is no hang if customize is invoked as a command instead of from the menu. 6) The hang can be prevented if build is loaded first. I'm trying to track this one down but I am at a loss on how to proceed. My luck with running the Cygwin version of gdb on XEmacs has been limited. In any case the system is nearly locked up once XEmacs hangs. XEmacs ignores signals once it is hung. david
