Hi Gerard.

>> When I try to modi scre in VFP, it gives an error :-
linLine14 or one of it's members..ColorSource expr evaluates to an illegal value' ...... and I cant open the form <<

I seem to remember this as a known issue, but it has been so long, I can't remember the exact nature of the problem. But it should be easy enough to fix. Just use the scx as a table in the command window, go to record number 11 and manually remove the .ColoSource reference.
