problem with zmacs regions

I notice this problem in xemacs 21.4 patch 22 running in linux in -nw mode. It does not happen in xemacs 21.4 patch 8 (also linux, nw). I mark a region and then try some command like untabify or sort lines and get a complaint that the region is not active. Judging by the (setf zmacs-regions nil) solves the problem. Interestingly, setting it back to t then leaves me in a state where the problem does not occur. Perhaps I did something to enter this weird state? I wonder what. And how I can tell. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
