Here are the steps to reproduce.
1. Right click ObjectDock icon in system tray in windows taskbar and select 'Configure ObjectDock'.
2. Two things happen at this point: ObjectDock configuration pop up window (containing Home, Settings, About tabs) opens and the ObjectDock UI tabs expands in the background.
3. Now, click anywhere on the screen, say Taskbar.
4. The ObjectDock configuration pop up window stays open, but the ObjectDock UI tabs collapses (gets hidden)
5. Now, click on the ObjectDock configuration pop up window.
6. You will see that the ObjectDock UI tabs expands and covers up the ObjectDock configuration pop up window.
7. Now, from this point forward, whenever you click on ObjectDock configuration pop up window the ObjectDock UI tabs expands and covers it up.
Try the above steps and you will see the behavior. This definitely should be fixed.
