I'm creating an Access database in Access 2000. I'm using a tab form for the entry screens. When I use the toolbox to add buttons on the form for saving, open/close another form, scroll to another record, anything I get the following error:

The expression On Click you entered as the event property setting produced the following errer: A problem occurre whil Microsoft Access was communicating with the OLE server or ActiveX Control.

*The expression may not result in the name of a macro, the name of a user-defined function, or [Event Procedure].
*There may have been an error evaluating the function, event, or macro.

I tested the buttons on a regular form and it works fine. I don't recall ever having this problem in Access 97 with Tab Forms. Does anyone have a suggestion?
