I see only 2 main problems:
1.) Not being able to set up keys to scroll east/west/north/south.
2.) It is VERY hard to move anything. Sometimes it works right away, sometimes it takes 15 attempts. Examples are barrels/chairs/garbage..picking up decapitated heads..hands. I cannot figure out why this happens, and I've played around with it for a long time trying to find a common occurrence when this happens. I'd say it's a pain to move/grab normal items at least 75% of the time. I've tried it in every resolution of the game.
I haven't played the demo yet, but in
Divine Divinity:
1.) Press CAPS-LOCK or hold SHIFT and use the mouse to scroll the screen.
2.) Click on or next to the object to get as close as possible before trying to move it. The object must be glowing white, not red, before you can move it.
I hope this helps and sorry if it doesn't!
