There is a trick you can try. On the form you want to receive focus, place a 1 x 1 pixel "TextBox" with a blank value, no border and transparent background. When you want to focus the form:
oform.myTextBox.SetFocus
oform.myTextBox.Click

I looked for exactly how I did it, could not locate - so this is my best recollection.
