Using VB6.

My app has a MDI form that is opened with WindowState = 2. Another form called menu is opened inside the MDI form.

How can I make the menu form open up centered in the MDI form? I tried placing Me.StartUpPosition = 1 in the menu form's LOAD(). However, when I do this, I get a VB error when running the form. The message starts with:
Function or interface marked as restricted

How can I get any form to startup centered in a MDI form?

Thanks,

Jerryt
