cant dock session manager on macosx

[keithop]

secure crt 8.0.2 build 118
on macosx el capitan 10.11.5

if I select session manager in view menu it appears minimised docked to the left.

if I click, it opens.

But it is not draggable, double clickable in title bar, or dockable in any way that I can find.

I just want it open on the left hand side at all times
