Internally, Access TextBox controls are actually "lightweight" controls--that is, they have trivial functionality. In fact, they don't allow editing! That sounds ridiculous, but what really happens is this: When a TextBox control receives the focus, it builds an identical, full-featured Windows TextBox control on top of it. The Access TextBox is really just a label control with additional properties for formatting and events. It's the Windows TextBox control where you do the real editing.
What's happening, then, is that the Windows TextBox is being built on top of BOTH your controls, hiding them. It looks just like the large Access control, so you don't realize it.
I think you can fix it though. Isn't the editing supposed to occur in the small text box? If you give the small text box the focus, it will build a small Windows text box control, which even though it's on top shouldn't cover the part of the larger text box where you put "Edit Mode". (If my assumption is wrong, perhaps you should consider doing it this way.)
