Recently, Arthur Fuller, a friend and colleague, had a mystery on his hands after updating an Access 2003 database to Access 2007. The 2003 version contained a custom toolbar that simply disappeared in Access 2007. He eventually found the custom toolbar hiding on the Add-Ins tab.
This 2007 behavior is as designed. When you open a legacy database that contains custom toolbars, there are two possibilities: If you replaced 2003's default menu bar with a custom bar object, 2007 will display the custom toolbar; when you open an .mdb file that maintains 2003's standard menu bar, 2007 displays custom toolbars on the Add-Ins tab. In this case, each group on 2007's Add-Ins tab corresponds to a custom toolbar from your .mdb file.
Custom toolbars must be visible in the 2003 database to appear on the Access 2007 Add-Ins tab. If an .mdb file doesn't contain a custom toolbar, Access 2007 hides the Add-Ins tab.
