You cancelled the previous operation

[bw]

Windows 2000, MS Access 2000.

I have a button on my main form that when clicked, opens a Calendar. After modifying
the Calendar form I was asked to save both of the forms, and I think I answered yes. In
any case, now when I click on the Calendar button, I get a message from Microsoft
Access that reads..."You cancelled the previous operation".

Now I can't even open the Calendar in design mode.

Can someone explain what's going on, and how do I get my Calendar back?

Thanks,
Bernie
