Russell,
I've never heard of this but you might try the following during your troubleshooting. Use the Add Class and Remove Class commands on each class stored in the VCX. After moving each class to a temporary VCX, try to edit it using MODIFY CLASS. If at some point, you can't, you may have a corrupted subclass and you will probably have to rebuild it.

add class class1 of myvcx to temp1
remove class class1 of myvcx

Once you verify/correct all the classes, you can use ADD CLASS to move them back into one VCX.

HTH.
