Lots load only in windows mode

[LizzyJ]

For the last month or so I've been having a strange issue with my occupied lots not loading in full screen mode. I uninstalled and reinstalled, removed all my downloads and the problem is still happening. Today I tried the game in windows mode and it loads lots fine. I noticed that when my game is in full screen no matter what resolution its on it always has a vertical letterbox thing happening. I tried to screen cap it, but the picture only showed my neighbourhood, so would that mean it's a driver issue? If so how do I uninstall my last set of driver updates? My monitor is a Viewsonic VG2030wm, my graphics card is a NVIDIA Geforce 7600GS and I've never had this issue with this hardware before. I've had my PC almost a year.
