Chris,
Thank you for the reply and advice. I have been popping answer dialogs all
morning. I still have no clue. I tried putting your code snippet in the stack
and card scripts, but nothing was trapped.
At this point, I have commented out everything in the card script except
openStack and preOpenStack. So, I have the IDENTICAL card script in two cards.
Card A works fine, card B fails. I can't figure it out! They do have
different controls... Is it possible that a control on the card could cause a
problem? even though the control isn't being accessed?
Wait a second....
Ok, found the problem. I have an image on the card that is (was) failing that
I use to hold an image temporarily. I set the fileName of that image to empty,
and now it works. Obviously, LiveCode crapped out when it tried to load the
image on the card. Even though I never accessed the image in code, and the
image is invisible, LiveCode didn't like the url set in the fileName of the
image. I should probability report the issue - LC should bail and should
probably report some type of error/warning.
Thanks for the help! In describing the problem to you, I began to think about
the controls, which led me to the answer.
