One of the things I'm trying to do in this stack is ensure that the userLevel is set to 3. Since the normal hierarchy would execute my stack startUp handler first (assuming you open the stack from the finder of course) and then the Home stack handler, the userlevel is "set" according to the preference card. I thought of two ways around this. One was simply to copy the Home stack startUp script into my startUp script. This works, but I'd rather not do this since it may change in the future and would be a maintenance problem. The second was simply to send the startUp message to the Home stack. The problem here is that when I do this, HyperCard goes into a loop until it stop with a recursion limit error. After playing around for a while and putting some debugging puts into my handler, I've determined that sending the startUp message to the Home stack somehow ends up calling my stack handler again! This is contrary to the normal progression of messages through the hierarchy. Is this a bug or just a screwy side effect of how startUp messages work. If it's not a bug, does anyone have a GOOD work around suggestion? I've found two work arounds, but don't like either. One is to copy the Home stack script as described above. The other is to use a global variable to hold a boolean as to weather my startUp handler has executed yet to conditionaly send the startup message to the Home stack. Thanks for any and all suggestions. P.S. I've tried this on both version 1.1 and 1.2 of HyperCard.
