PS4 Log Window size problem

So I somehow managed to make the log window take up 4/5ths of the screen on PS4. No idea how. Similarly, no idea how to change it back again. I've tried using the touch-pad to grab the top-right corner but whenever I click down the touch pad to drag it, I just get tabbed around the various stops in the HUD.

Anyone know how to fix this? :(

Thanks.

Never mind - I switched off the touch-pad support and used the virtual-mouse biz to sort it out. What a pita.
