HyperCard: Corrupted Stack (HyperCard Stack Won‘t Open) (11/92)

When trying to open a HyperCard stack that has been corrupted, one of three
things may happen:

* HyperCard opens the Home stack instead of the stack desired, and doesn't
let the user open the desired stack at all.

* HyperCard seems to open and load, but instantly quits to the Finder
without showing any card windows.

* HyperCard reports an error has occurred with an error number, and
exit either to the Home stack or to the Finder.

Here are the solutions:

* A utility named CanOpener available from Abbot Systems, Inc., will
extract all text, PICT, icon and sound resources from most stacks that
have been corrupted. All of the stack scripts, including the scripts of
buttons, fields, cards, etc., will be recovered as a text resource.

* If all else fails, restore the most recent back-up of the stack.

And some tips for prevention:

* If possible, avoid creating and modifying stacks on a floppy disk.

* Compact your stack often.

* When developing a stack, work on a copy -- and ALWAYS make back-ups.
