>FWIW, I have never had this problem, because my framework doesn't use a DoForm method. Rather, all of my forms register themselves with the forms manager when they are started. This keeps me out of the parameter passing mess, lets me use DO FORM whenever I want, and avoids trouble like you are having here.

Erik,

My form manager does have a DoForm method, but modal child forms are called and owned by the parent form directly.
