I have a background script wich, when it gets an openCard
message it waits a certain amount of time, then does a go to next
card. This is bad since this thing recurses... and hypercard complains
only a few cards into the stack. It is essentially a 'hands off' slide show,
i.e. the gotonextcard isnt imbedded in a mouseUp message, but is timed.
is there another way i should be doing this?

Here is one way to get around this problem: - instead of using the openCard message to continue the slide show, put the whole sequence in a repeat loop located in the handler that starts the slide show. For instance, on mouseUp repeat for the number of cards wait 5 seconds go to next card end repeat end mouseUp jeanne a. e. devoto jdevoto@apple.com

Many people have called me for help on this very problem. (I don't have the time to help everyone all the time, yet I love helping people out. This is a Catch Hyper22.) Never depend upon "openCard" handlers to control an automatic/slide-show type stack. Such a script should be done with one script, possibly calling sub-scripts for each card. By using the 'openCard' or 'closeCard' handlers, after about 5-7 cards (6 is the magic number) an error reports "Too much recursion." You can only call a handler 5 levels deep before the error occurs. So, the best way around this is to create a 'mouseUp' which controls the slide-show. I believe that someone else already posted such a similar suggestion. I just wanted to put my two cents in (after I spent 5 hours telling one guy not to depend on 'openCard' handlers.
