Main Vertical tool palette split

So I was rearranging some tool palettes when my main vertical tool palette disappeared, not sure why. I worked to get it back by turning on Main 1 and Main 2 palettes. For some reason these two were split into 2 palettes which I don’t recall being 2. So I put them back to the side vertical area and they now have a line between them. This is important because I want to put a palette below them and only a single row palette will now fit. Any ideas?

The vertical toolbar should be Main. Also it should be controlled by the tabs along the top of the screen, if you right click the Standard tab and click properties the sidebar should be set to Main.


Just noticed there’s a setting in Options as well, Sidebar visable.


Thanks Mark, that did it.
