How do I remove or move the tool taskbar pane on right?

Not sure where to ask this so feel free to move it to the correct area.

I'm using Adobe Acrobat Pro DC and there is a toolbar to the far right where the scroll bar normally goes.  How do I move it to another location or remove it?  I don't want to hide it.  When I move the mouse to the right I want to be able to scroll down using the scroll bar.  I keep opening the tool taskbar because of it's location on the far right.  It's annoying, inconvenient and counter productive.  I need to either move it to the far left, to the tool bar location above or to remove it completely.  How do I do that?
