widget (toolbar, menubar, scrollbar) not redrawn in time

Recently I've noticed that if XEmacs is covered, and you uncover it, e.g. by clicking on the taskbar so that the mouse is not in the frame once it's exposed, everything is redrawn correctly *EXCEPT* the menubars/toolbars/scrollbars/gutters -- i.e. the stuff drawn by windows. Once you move the mouse into the frame, or any other event (e.g. timer) happens, it gets redrawn. For me, this can always be reproduced by iconifying and then clicking on the taskbar. It seems that it's most likely Jonathan's changes, because he was messing around with mswin expose handling; but it may be an andy thing as well. (btw it happens even when gutters are made invisible.) Could one of you look at this (preferably) or give me hints as to where the problem might lie? -- Ben In order to save my hands, I am cutting back on my mail. I also write as succinctly as possible -- please don't be offended. If you send me mail, you _will_ get a response, but please be patient, especially for XEmacs-related mail. If you need an immediate response and it is not apparent in your message, please say so. Thanks for your understanding. See also http://www.666.com/ben/chronic-pain/
