UI covers Diagram / Query / Results tabs in Builder

Running Toad Data Point 6.0.5

I have an unfortunate habit of clicking in exactly the wrong place in Toad in the Query Builder. Specifically, the border between the Diagram / Query / Results tabs and the little bar that shows "Tutorial", "Open Query" etc. at the very bottom.

When I click there (and presumably drag, none of this is intentional), it brings up an unknown bar that looks like it would be the header of a new pane, that as far as I can tell, does nothing. Furthermore, I have not figured out how to get rid of it.

The problem is, this extra pane covers up the Diagram/Query/Results tabs. Clicking on the down arrow and x button to the right does not do anything, and expanding the pane to try to find some options is also useless. The internet has not provided me any answers, so I was hoping someone here might know a solution? My current workaround is to exit TOAD completely, and re-launch. Obviously sub-optimal, as I am working on something when this happens.

Does anyone know how to get rid of this thing without exiting the program?

Edit: Added screenshot for clarity

Very strange indeed. Have never seen this and I can't reproduce, at least not in release 6.3.

Can you pgrade to the latest release and tell us if it's still happening?
