Hi Les,
I too had this same or similar problem for a while. The error message I got
was 'program: C:\finnigan\isodat nt\global\bin\workspace.exe - abnormal
program termination - (press retry to debug program)'. This error window
coincided with a lack of jump from N2 to CO2 configuration. If I clicked any
of the buttons the acquisition screen terminated. If I left the screen alone
the sample schedule would continue, but could receive the same error again
and open a new error window.  
I too attempted reloads of Isodat, recalibrated the mass scale, deleted and
recreated jump files, erased the entire computers hard drive and started
over, and removed and replaced memory (as I always received a memory error
after I closed the error message mentioned above). None of this solved the
problem. I was able to narrow down the fact that the jump file was becoming
corrupt for some reason after creation. Deleting and recreating this file
would solve the problem for a time, but would always reoccur, however, not
in a predictable number of jumps or other factors I looked at.
Eventually, I replaced the computer with another that has dual processors
(don't think this matters) and 1GB of RAM memory (I do think this matters).
I have not seen this error message again. I am not certain that the increase
in memory was the solution; perhaps the old computer had another problem
within the motherboard or memory cards themselves. However, when I tried to
reproduce this error on the new computer by loading the memory and
processors with open programs while acquiring data I did receive an error
message, however it was different, go figure (sorry did not write it down).
This time the jump file was fine and did not get corrupted and once the
memory was freed up again the error messages stopped. At any rate, I have
not seen this error or had trouble jumping since the change in computer. I
have had runs totaling 150 samples and have probably run in excess of 5000
samples so far without problem. I can dual task using internet, email, word
and excel without having a problem.
I realize this is not really a certified solution, but may be something to
look at. If you are able to borrow a high memory system to test, it might
save you the expense of buying a system that is not the solution. I any case
hope this helps. If you discover the real problem I would be very interested
in your findings

yes, it is when it makes the jump to CO2 that the problem arises. I will
check to see if the "?" is in the window and try to see if the backup
program will help.  So far that has not helped.  Thanks for your help, I
really appreciate   it!  Les
