Nick,

You are right, it's been too long since I read that help topic. But that doesn't exactly explain why the heck it doesn't reliably do what the help file says it's supposed to do and forcing a call to Draw(). *bg*

I'll amend my recommendation to:

ThisForm.SetAll("Enabled", .F., "cmd")
Thisform.Refresh()
doevents
* do the long running thing

I use the .Refresh of buttons all the time with code something like this:

this.Enabled = f( SomethingAboutSomeFieldOfTheCurrentRow )

without experiencing paint problems.

>A graphical object, such as a text box, a rectangle, or a command button, that you place on a form to display data, perform an action, or make the form easier to read. Visual FoxPro controls include check boxes, edit boxes, labels, lines, images, shapes, and so on.
