For the last few years I have been happily using Fritz 5.32 running under
Windows 98. Just in the past few days I have been getting the following
error message shortly after setting up a position and asking Fritz to do
"Correspondence Chess" analysis:

"This program has performed an illegal operation and will be shut down. If
the problem persists, contact the program vendor".

The only thing I can think of is that I may be shorter on disc space than I
was. Any ideas, please?

Thanks in anticipation.
