I ran into a bug in PENG that seems worthy of
note. Under certain circumstances PENG crashes
when it tries to open a previously saved PCF file,
thus making the file useless. After some time
trying to figure out what the problem is, I think
I've narrowed it down to saving certain PCF files
that have grouped items in them. I've learned
not to group items then save the PCF file, and
to also save under various filenames so as not
to lose to much work should I encounter this problem
again.
