A different screen resolution problem

I'm running a Win 7 Ultimate system with 6GB, i7/950, & ATI 5870 and a Viewsonic VP2650wb running at 1920 x 1200. No problems with most games, but I just downloaded DarkFalls: Lost Souls, and once it starts, the cell phone appears with only the top 1/3 of it visible on the screen. There is no way to drag it higher, and I can't use any of the functions below the phone's display screen. I *can* make the phone slip even lower, by clicking on one of the symbols (I forget which one), so that only the top 1/4inch of the phone shows, and clicking on that then makes the phone slide back up into it's 1/3-visible position, but nothing seems to make the entire phone visible. I wonder if I'm missing anything else off the bottom of my screen? I've tried lots of things, including cursing the game designers and setting my screen resolution to 1600 x 1200, but nothing works so far. Very, very annoying for a new game that should have been checked out on a large number of monitors/video adapters (and mine are relatively new & common!)

And the game has *no* options whatsoever for setting screen resolution, which seems a tad odd.

Anyone else out there run into this mess?
