1. How do you deactivate the tabs? I cannot seem to drag the widget across to the left handside to deactivate
You can always click the "Remove" link in the bottom left corner of the widget you want to remove, but that will completely delete the widget, so you will have to recreate is if you want to add it back.
Another option is to use the Widget Context settings for the widget to hide it everywhere.
You may also need to remove the title for that tab in the settings for the actual Tabshow widget.
2. In the template TabsShow 4 - 10 has no text yet, text is still visible on the home page? how is this possible?
I'm not sure what you're referring to here. Can you provide a link?
