Hi Nadya

Sorry i can't help you with the problem, as I don't have/use GridHighlighter.
I'm interested in the wording in your message box:

> =messagebox("You can not clone a record while you haven't saved your changes!",48,'Clone function is

I would have said:
"You cannot clone a record until you have saved your changes!"
or:
"You must save your changes before you can clone a record ".

I was wondering if this was a more American way of saying the same thing. Or is it a result of the fact that, in VFP, we don't have a Do ... UNTIL construct, only a Do ... WHILE, so the programmer's brain gets into the mindset of "while this condition is not true give them this message" rather than "give them this message until this condition is true" :-)
