We have a stack of HC 2.0v2 350+ cards that we use to keep track of students in
the Psychology Department here. One day, for no apparent reason, the stack
began shutting down with a window that said "Unexpected error 5454" with the
only button available being "quit".
Further investigation showed that:
"mark cards where" produced the "Unexpected error 5454"
card # 349 did not exist ("no such card" on a go to card 349 command),
the "go to card 350" or "go to card 351" command would produce the "unexpected
error 5454"
Pressing the right arrow key when on card #348 results in no action
Pressing the left arrow key when on card #352 results in "Unexpected error
5454"
Clearly something major is dead. Perhaps internal pointers are gone? Card
numbers are supposed to be consecutive and always renumbered when a card is
deleted etc. Copying the stack in the finder does not resolve it. I am
presently writing a button to copy the unbroken cards and paste them in another
stack.
Any hints about why this would have occured?
