Starting in version 6.0 Service Pack 3, the Summary tab contains a predefined set of widgets. In addition, the tab and all the predefined widgets are "read-only". This means that regular tab and widget operations are not allowed in this tab.
If you renamed the Summary tab in your previous Control Manager version (for example, from Summary to My Summary), the tab will be migrated as-is after you upgrade to version 6.0 Service Pack 3.
If you did not rename the Summary tab and then upgraded to version 6.0 Service Pack 3, one of two things can happen.
You do not see the old Summary tab (the tab you were using in the previous version). This happens if you did not change the tab's settings, such as its layout or auto-fit setting, in the previous version. You can bring back this tab by following the steps below.
There are two Summary tabs - the new read-only tab and the old tab. This happens if you changed the old tab's settings. To avoid confusion, rename the old tab.
Follow these steps to bring back the old Summary tab.
