Hmm, I'm pretty sure it was in windowed mode last time I tried, but you might be onto something there.

I'll let you know how it turns out! So my Maximizer.ini should be like this?

[code:1]
resolution = 1360 x 450
taskbar = 1 (because I need the window's controls to span)
[/code:1]

[Edit] Oh, and thanks for the help!
