I was able to duplicate the cause of the crash.

Anyway -- the cause of crash -- There are 100 fields on the card and 20 of
them are off the bottom edge. I choose select all, copy all, make a new
card, go to that card and then everything freezes (there is no spinning
beach ball and no indication that the program has not crashed). If you wait
like 10 minutes the freeze goes away but then if you choose paste, nothing
pastes. So I try copying just 10 of the fields, one of which is off the
bottom edge. When I do this -- it takes a very long time to go to the next
card and the paste works although the field that was off the edge of the
card pastes into the middle of the card.
Hi Bill,
As I have reported on several occasions, the Revolution IDE has various problems when dealing with cards that contain a larger number of fields.
One cause - for some of the problems - can be located in the frontscripts of the IDE; you could try to find out if it applies in your case:
Part of the frontscripts is the script of button "revtable" of stack "revlibrary", which is "inserted into front" when the IDE starts:
Button "revtable" contains the "table library" for "improved table field interaction with databases" as the header says, but produces problems for any type of application, i.e. also for such without table fields or spreadsheets as it is in inadequately insulated from other types of applications.
There are two instances of a loop with "number of fields" in the script that can cause problems for cards with lots of fields.
The first - in the "on preopenstack" handler - is inoperative because the "on" line is commented.(???)
The second is contained in the "revDeleteCellFields" handler which is used among others in the "non-rev" handlers
- focusin - focusout - exitfield - closefield - scrollbardrag - mouseup
Of these handlers "focusin", "focusout", and "exitfield" are those that are insuffiently insulated against non-cell related objects, which means that the Rev IDE begins looping over all fields on a card - in any Revolution stack even if it does not contain a "table" - when one of the three messages are sent.
Most of my problems with stacks containg larger number of fields went away when I substituted the script of button "revtable" with an improved script.
I reported this in a post to the improvement list "Some speed and other problems solved" on April 16. Kevin Miller informed me on May 10 that he had included this problem in the bug-auditing process.
You can test if your problem could be caused by this script by removing the script of btn "revtable" from front.

Wilhelm Sanke
