I was quite happy to see that the control panel on Full Screen had an expanding button.
I had the temerity to choose one of the profile options under Tools=> Customize Interface=>
Select Profile (ToolbarProfiles?) so that button is no gone. The change also affects some items
not showing on the Main Control (Tool) bar. Using the [X] button (Customize Interface) does not revert.
Any way of getting it back without having to reinstall by deleting cache and preferences ?
