The good reviews and feedback made me buy this game, however the fact that you can't adjust resolution - or actually run it fullscreen - on a 4:3 monitor makes it unplayable.
I use an old CRT with a decent refresh rate and so far this problem has never come up.
Any tips on how I could make the game scale?
(Switching to a higher resolution is *not* an option, I want to keep my refresh rate above 100 Hz).
I feel your pain. While not perfect optimally, have you tried manually moving the window from left to right to access what you need during different aspects of the game? While the height of the window was fine, on my moniter, it was just too wide, but I could still play, and battle just fine by doing this.

(Yes it was a little bit of a pain sometimes, but is quite playable..at least in my situation)
