I have a stack that allows you to create a number of cards, and when you click
on a button it looks at a given line on a given field, takes a numerical value
placed on that line, adds it to a container, then goes to the next card, etc.
until it has done all the cards necessary.  While it is going from card to card
I have it get a user defined function in the stack script that will count the
number of cards to be tallied and then figure out what percentage of the total
number of cards to be tallied the current card represents. It then places that
percentage value in the message box.  (Example:  on card 1 (of 10 to be counted
say) it displays in the message box:  "10%", on card 2 "20%" and so on.)  Now
in HyperCard (HC) 1.2.5 this process starts to visibly slow down after getting
about 33% of the way through a large group of cards (i.e., more than 24 cards).
I have converted the stack to a SuperCard project and this operation runs with
NO DEGRADATION in speed!

What's different about SuperCard 1.5 and HC 1.2.5 (running on an SE/30 with
system 6.0.4)  that would cause such a slow down?  (I'm getting more and more
tempted to switch over to SuperCard.)

Thanks for the info.
