My first question is has anyone ever got to get Alt+Tab working with this game? I've tried it with the widescreen mod, setting the aspect ratio in the NVidia Control Panel, or without both and in the three cases Alt+Tab didn't work. I even ran that sdbinst command from the support section but it didn't nothing.

My second question is related to the slow startup of the game. It's 20+ seconds until the game starts and during that time I cannot do anything else on my screen.

I'd greatly appreciate any help.

Thank you, that helped me!
Maybe see if you can reply to your own post and mark that as the solution?
