On my Mac at home, I am having a lot of trouble with HyperCard hanging
at unpredictable times. Sometimes it hangs during stack compaction,
sometimes when I am bringing up a script to edit (a frame but no script
appears), sometimes when moving to the next card, sometimes when a button
is clicked that should bring up a hidden field, and often when moving
from one stack to another (the card of the new stack will be shown, but
the Mac is hung). When I say "hung", the cursor still tracks the mouse,
but I can do nothing other than hit the reset button to reboot.
The Mac is an original 128K, upgraded to a 2-Meg Plus-equivalent with a
Dove 548S (I think -- anyway Dove SCSI and 2 Megs), Lonely Heifer ROM,
System 6.0.2, HyperCard 1.2.2, Jasmine Direct Drive 80 with 8.5Megs space
but probably well fragmented. I have tried many things, such as removing
all inits, both using "init cdev" and physically; removing Suitcase II
and all DAs as well, so it is almost a bare System, running under either
MultiFinder or Finder with and without 512KE XPRAM INIT. Sometimes there will
be hours between hangs, sometimes minutes. I have a superstitious
feeling it happens less often if the stacks are well compacted.
The stack set is 10 stacks totalling around 2.5 Megs, using a special Home
stack, but none of this happens on my Mac at work (2.5 Meg Plus) or
on my collaborators' Macs of various types. Any ideas?
A second problem that happens on my Mac at work and on my collaborator's Plus
is the frequent appearance of an empty dialogue box ( no text, but a
default button to click). If you click on the default button, the box
goes away, but we don't know what it means. We thought at one stage it
meant "out of memory" but that seems unlikely (still possible, though).
It again seems not to happen so often if the stack is compacted, but this
also might be superstition.

If the universe transcends formal methods, it might be interesting.
