>Dan,
>The form (with the resize code) was VMP, as were the original textboxes I worked with. I tried the addobject() with plain VFP which didn't resize at all and with VMP which not only didn't resize but moved to top=0 and left=0 and width = original class size, as I said earlier.

Barbara- I tested with what I could put together that you are doing:
Blank form, one button with click code:

SET CLASSLIB TO c:\myclasses.vcx
THISFORM.Addobject('mytext1','mytext')
THISFORM.MyText1.Left = 50
THISFORM.MyText1.Top = 50
THISFORM.MyText1.Visible = .T.

Running the form, clicking the button, and resizing the form does not cause the behavior you describe...

Can you break your process down incrementally until you find the sinister factor?
