Good Morning All.

Unfortunately we seem to have celebrated too early since we get now
reports from one single MS Excel user about corrupted files.
And now things become really messy:

1) what was the best way to test Excel files on Excel (various
versions?)=A0
2) why all of this just recently, what has really changed and causes
it?

Best regards
Andreas
