Hello,

I work with VFP5. There's this peculiar problem with the REPORTs and 1-M grids.

I have 2 grids, in a 1-M relationship, either with :-

1. Programmatic SET RELATION TO, SET SKIP TO, or
2. use of LinkMaster and ChildOrder in the child grid.

These grids reside in a Private DS form, and work OK under normal circumstances.

However, if I do a MODIFY REPORT or REPORT FORM ... PREVIEW on ANY report(s), and then run the form, I get an Illegal Operation (Exception 10H in vfp.exe) and vfp terminates abnormally.

Has anyone any idea why this is hapenning?
