It's weird but it was only happening on the campaign tutorial map, I was just using that to test the resolution change and it kept knocking down to the default. However when I started a full campaign it was fine.

That's only the start of my problems though, on the battle map the cursor doesn't appear to do what it's told, it's fine clicking on buttons and the unit banners but when I click on the ground for a unit to move there it moves to a different position. It seems to be around half a screen closer to my POV, so if I click on somewhere in the centre of the screen the unit moves to right in front of my POV, not where I clicked.

I was trying to do the tutorial again and because you have to click on the flag at the beginning to progress it doesn't let you do anything else, instead I get a very irate Sean Pertwee (the general) shouting insults at me!

Can anyone help?
