I am using Access 2007. I have set file to open a Form I have labeled Main Menu. From the Main Menu I have control buttons to open another 5 Forms. I have set tabs to appear across the top. What has started to happen is when I now open a Form from the main menu it is appearing behind the main menu screen and not on top as it had previously. Clicking on the tab does not work either. I have to Close the Main Menu Form to work in the underlying Form. I realise I could put some code to Close the Main Menu Form and the use code to reopen it again on the other Forms. I was wondering why it happened and if there is any way to reverse what has happened.
