RE: XEmacs from CVS is randomly crashing and locking up

Um ... no. In fact, I'm not quite sure what you're talking about. Let's see. It looks like you made that suggestion to Paul Stodghill , who was building for cygwin. I'm doing a native build using VC5.0 (my fault, I should have clarified that in the beginning: Stodghill saw it first on cygwin; Krause confirmed it on windows native), so I am already using the version from nt.c. At least I think I am. M-x describe-installation OS version: Microsoft Windows 2000 [Version 5.00.2195] OS: Windows_NT XEmacs 21.5-b1 \"anise\" configured for `i586-pc-win32'.
