I've discovered that visual effects ("lock screen" in closeCard, followed by "unlock screen with ..." in openCard) don't work when one is using a monitor that supports either colour or gray scales, and you have that feature turned on. Switching back to Black & White (in Monitors in the Control Panel) makes them work again, immediately. 1. Anyone know why? I haven't seen this documented anywhere. 2. Is there a workaround? Or a fix in HC 2.0? David Sherman -- Moderator, mail.yiddish { uunet!attcan att utzoo }!lsuc!dave dave@lsuc.on.ca

This is documented somewhere, but I don't think it's in the HyperCard User's Guide. It's not a bug, it's a feature. There have been a couple of threads in this Newsgroup asking for a way to set the monitor type with Hypertalk or an XCMD. The consensus seems to be that this can't and shouldn't be done, since the Control Panel is the user's exclusive domain, never to be altered by programs. Of course, you can open your stack with a message telling the user to set the monitor type (and perhaps the authoring/scripting/whatever level of Hypercard). This sure detracts from programs designed for naive users, though. -john
