[AccessD] Access 2010 cannot get at the form I opened.

Actually, I believe there are 3 separate states (and 3 separate behaviors):
1) modal
2) modeless
3) dialog

With Modal, you can still switch to a different window; also, any code after
the OpenForm does not execute. With modeless, the code after the openform
does continue to execute. With Dialog, no other windows can be activated
until that window is closed.
