Pascal,
You can enter new values when using a combo box, but the information will not automatically be part of the list. You must add the information to the list in the Valid() or LostFocus() methods.

I have found that if I am letting users enter new information that I have a textbox bound to the appropriate field, and an overlapping combo box. If the user clicks on the combo box 'button' it comes to the fore and drops down. In the combo box valid I sent it to the back and put the data into the textbox.

This is pretty simplified, but I hope it gives you the idea.
