Can you use a statuette and then walk or run? Even when walking a frog is relatively fast.
If you hit Caps Lock, or hold the Shift key down, and move the screen focus quickly, does that also cause problems?
Try lowering your hardware sound acceleration a notch (click Start | Run, type in dxdiag and hit Enter, then switch to the sound tab). A couple people had problems with the game crashing more often when running than walking, though that was also associated with going through doorways. The fix for that might help you, as well.
