Heavy load under native win32 xemacs 21.5

Hi, For quite a long time, I have observed that xemacs may turn up to consume CPU even doing nothing (in the range 25%-95%). I have not tried to reproduce that under vanilla xemacs, my usual configuration runs gnus and buffers to edit program files. I have used spy++ to look at the messages sent to the xemacs window, and there is a real high number of WM_CTLCOLORSCROLLBAR messages processed, which seems a bit strange to me. Is there any reason for that ? I don't see why messages should be processed while doing nothing. Any insight on this problem would be welcome, Greetings, -- Fabrice _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
