difference between UF5 and UF6

I happened to find out that certain formulas can no longer be used in UF5. This applies to mmf.ufm. In UF6 is a totally new series mmf.ufm.
I don't know if it applies to more formulas.

When formulas are updated, the formula author should be careful to keep them compatible with older versions. I get the problem in v5 too with mmf.ufm, and will look into it to see if I can fix it.

Okay, Thank jou Frederik, greetings, Liesbeth

The problem was that the mmf.ufm file used Mac line endings which confused UF5. I've now uploaded a fixed version of the file.

Thanks for your intervention Frederik,
