Recovery of a corrupted stack -- actual case study

[Erik Hansen]

David,

i used your ideas on my bad stack
"songsDB" with the most amazing results!

backgroundbehavior = true for both stacks

1. make a fresh stack
2. copy the bad stack script,
3. copy the bad stack group(s),
   one in this case containing all controls
4. copy all 400 pages of the bad stack

all of the contents of all of the fields
transfered correctly.
buttons to find, sort, limit,
checkbox which fields to display
for printing, all worked correctly.

the bad stack was 137K,
the new one: 16 Megabytes!

then the corker, the "bad" stack somehow
auto-corrected and began to work again!
