For reasons that I don't think were ever made clear in the Apple HC book, HC needs to be run from an unlocked disk. What I would like to be able to do is lock my hard disk and let young'uns explore and run HC, saving their files on a floppy. But just moving HC and Home to an unlocked floppy doesn't work. I'm not sure why, but I guess HC must be trying to write something to the System Folder on the locked disk, though I can't see what. The alternative that does work is clumsy: also put a copy of System Folder on the floppy, and reboot. Anyone have a better workaround? How about HC 2.0?

Sounds like you have an old version of HC like 1.0*.

One reason HC (even 1.2.5 under System 6.0.5) won't run with a locked startup disk is that for some reason it wants to overwrite the clipboard file in the System Folder as it starts up. You can confirm this by doing a "Get Info" on this file, and clicking the "Locked" checkbox, to lock the file. Presto: HC will not run! If there is no clipboard file, it will insist on creating one. So what gives? Is there a way of getting HC to leave that file alone?? Thanks Hector Levesque Dept. of Computer Science U. of Toronto hector@ai.toronto.edu

In HyperCard 1.2.5 and earlier Bill made a call to UnloadScrap to free up the memory that the clipboard may be taking. If this returned an error code (which will happen if the Scrap Manager can't write to the Clipboard file), HyperCard would quit. Silly, eh? Well guess what? We thought it was silly too, and "fixed" it in 2.0. You should be able to run HyperCard 2.0 with a locked startup disk. Martin Gannholm Apple Computer Exclaimer !!!
