MDI Parent form changes other forms' sizes, how do I make it stop?

[Kiegs219]

When the forms appear in the MDI Parent form, the size of the forms is not the same as it in design mode. My form interface looks really bad when the form is stretched. Is there any way not to let the user to resize the form? Is there a way for the form to keep it's original size when it loads in the MDI parent form? Thanks
