In an Access 2 db, a cb no longer allows one to type inside without crashing Access. It worked for months. A new cb did not resolve the matter.

What could be the problem?

Look at the RecordSource. If its a query check to make sure that it is valid by coping it into a Query Object (Use the SQL view).

Next check the Events of the Combo box. It is possible that there is no error trapping and the event is failing.

Hope this helps
