The reason is that the WindowKind of the window has been set to indicate that
the window belongs to the DA rather than to indicate that the window is a
dialog.  The best fix is to save, set and restore the WindowKind around the
SetIText call -- like this (pardon if my C is a bit rutsy):

SetNo(theNo,itemNo)  /* set the Dialog Item "itemNo" to the  number "theNo" */
int itemNo;
double theNo;
{
	Str255 theText;
	int oldkind;

	ftoa(theText,theNo);   /* convert theNo to a Pstring */
	oldkind = dce->dCtlWindow->windowKind;
	dce->dCtlWindow->windowKind = dialogKind;
	SetIText(DItemHandle(itemNo),theText);
	dce->dCtlWindow->windowKind = oldkind;
}


Just for fun I'll give another approch (not as good as above but better
than calling DrawDialog) is to InvalRect the item's rectangle and let
the normal update mechanism handle it.

I hope that there aren't too many lies here...
