Question

Crash resulting in 0kb file. So frustrated!

I've been experiencing consistent problems with
M020, mostly having to do with Unhandled
exceptions, though at other times we've seen an
error stating that the volume we're saving to is
full (it's not) which isn't resolved until we do a
'save as' with a different file name, on the same
volume or elsewhere.

This isn't isolated to just one user or machine
it's affecting at least two machines and two
users, possibly more...

What compelled me to post today was a crash that
left one user's file corrupted. It literally
erased EVERY piece of data from the file. The
xmcd file is now 0kb and unsalvageable as far as I
can tell. I'm not sure what to do at this point,
we've performed countless reinstalls.

I wonder if part of the problem with us and why
it's so difficult to find support has to do with
the fact I've never encountered anyone else that
uses the software the way we do. We're a
structural engineering firm and I don't know if
the software is usually utilized the way we use
it, though I don't think we're really pushing the
envelope as far as MathCAD's capabilities are
concerned.

Has anyone experienced similar issues and resolved
them? I'd love some suggestions.

Mathcad 14 crashes regularly. For me, I would say several times a day, every day. This behavior seems especially prevalent when I'm doing anything with symbolics. I save my work regularly, and often make a backup copy of any important worksheet that I'm working on. So far (famous last words!) I have not had a file destroyed, but you are not the first to report it.

Another approach that can help is to shut Mathcad down every 30-60 mins and restart it

Interesting. I very rarely get M14 crashes ... in fact, I can't remember the last time it did (not that that means particularly much, given the beat-up collection of off-gray matter I possess).

OTOH, I rarely do any symbolics in it, given it's prediliction for taking eternity to come up with a result that needs careful interpretation.

Well, maybe I was being a little mean yesterday, but when I wrote that Mathcad had in fact just crashed. I don't work all day every day in Mathcad, but when I do work all day in it I expect at least one crash.

It does definitely seem to be linked to symbolics for me. When I have been playing around with symbolics for a while a crash is so likely I view it as almost certain. Large data sets seem to up the chances too. When it crashed yesterday I was in a worksheet that reads in three data files with about 350,000 points each. I was clicking around in the second y-axis of a graph that was displaying zoomed in sections of all three data sets, when it was suddenly bye bye Mathcad....
