>Check code in Resize method of the form.

There's nothing much there, and if I comment it out and replace it with DODEFAULT(), nothing changes. The RESIZE code won't fire in any case until the event occurs, and the event can't occur if I can't even grab an edge of the form to drag it to a different size.

There is something I held back: the form contains another form, fired up with this code:

	WITH thisform
		.AddProperty("oScrollForm",CREATEOBJECT("frmIntkScroller",this))
		.oScrollForm.Move(lnLeft,lnTop,lnWidth,lnHeight) && left, top, width, height
		SHOW WINDOW (.oScrollForm.Name) IN WINDOW (.Name)
	ENDWITH && thisform

I'd remove it temporarily to see if that makes a difference, but there are so many references to thisform.oScrollForm.[something] that it is difficult to run without it.
