Hi,
Is there a way to pause and un-pause game using only a mouse input?
I'm trying to play NWN2 on tablet and this is the only thing that bugs me...

I don't know if one is already made like that, but the interface is XML, so if you know XML you can make an extra interface widget that will accept a mouse press to pause the game, or maybe just add that function to an existing UI element, like tapping the mini-map to pause.
