Hi Christian.

>> Mmh, not exactly: I want to make a difference between a value entered with the keyboard or selected with the mouse using the drop down list of the combobox. <<

Why? I'm just curious...what are you trying to accomplish here? I don't see that it really makes a difference HOW the item in the list is selected (via mouse or keyboard) as long as it IS a value in the list. Or am I missing something really findamental here?
