Updated to 5.77 - lost control of move items

[ChristopherT]

Hi, I just upgraded to 5.77 - & lost control of move items.
I cannot move items anymore.

Looking through all of the mouse modifiers, I cannot find the basic function that existed previously.
Which should be click / hold mouse button to grab item and move it.
Could someone please help with the correct mouse settings.

I also now have made some wrong changes to mouse modifiers and now cannot seem to turn them off.
PITA.

I saved Reaper config before updating.
Is there a way to reset / import my previous actions via the saved Reaper config?

Or how do I use saved config to restore everything back to 5.4
