I don't change any of the GHL properties. I simple add the code

this.parent.gridhighlighter1.highlight_row() to code in afterrowcolumnchange.

I designed the form and put GHL in afterwards.

The form is often altered - would that matter?

Should I remove GHL from the form and then put it back again?

BTW - it happens once in a while - not all the time.

Thanks for replying
