Just to save anybody else the trouble of pointing it out, it turns out that the Width property is always read-only when it applies to a control contained in a Column object.

In the form designer, the Width property of all the controls in every column of every grid I've checked shows as 10. Yet when a form is run, controls in a grid apparently take on the width of the column they're contained in... but evidently without actually changing the control's Width property, according to the debugger. So the question is: at run time, when does VFP calculate the width of a control contained in a Column object, and where does it store this value?
