Hm, that does seem odd.

I am able to move all windows that have a 'title-bar' by left-clicking and holding with my mouse on the title-area, which displays the window name (Solo, Target, Key Items... etc.). By holding down the shift key, I can move them by left-clicking (holding down) at any part of them.

That includes even the 'help-bar' on the top left-quadrant.

As far as I am aware, the log-window can be resized only via the options under the Windows section under Config, similar to the old/current interface.
