Ok, Ive tried all the fixes suggested, Admin mode, Window mode, the controller fixed it until I had to unplug the controller, now it doesn't fix it regardless of rebooting. obviously this is a problem that hasn't been fixed. It seriously looks like something to do with the a hardware cursor... maybe? Either way im looking at asking for a refund as this is unplayable and sofar doesn't look like anyone is fixed it. any help appreciated ...

Now that we have got Steam on Linux what about a Linux version of this?

so when i ove the mouse its lagging tried everything used other graphics card used it in admin mode dosent help but i want to play it fieldrunners is so great ^^

There seems to be a few broken achievements, like the Purple Heart one where you have to get a victory with 1 life left, which i got and the game even said so, but then it locked up again on Steam. Please fix your achievements.

I had unlocked everything up to Skyway, then I didn't play for a couple of days, today I launched the game and everything was locked. I don't play this game on other platforms, I didn't make any change to my OS. Any thoughts?
