I can reproduce xlsior's problem: immediately upon starting a new world (level 1-1 works) move the mouse into the Northeast corner of the screen and leave it there. Plobb will not start following the mouse until it's within a certain range; he'll continue northward, right off the screen, and wrap around to be just out of sight in the south.
It seems that most of the time I get Plobb to walk off an edge of the screen, he stops, and I must move the mouse cursor close to him to get him moving again. I believe this is new to 1.0.1.
