Does the laptop have a touch screen?
Bryce only really works with a relative input. Like a mouse (in most cases). With a mouse, as you move it it sends a signal that moves the Bryce object on screen. When you stop moving the mouse it stops sending the signal and the Bryce object stops moving.
With an absolute device, like a Wacom pen, or a touch screen the it send a signal when you move off center, but when you stop moving it doesn’t stop sending the signal. So Bryce keeps receiving a signal to move the object and you get the constant spinning. I have the same problem with my Wacom pen and have to use a mouse.
Anyway, none of this really helps you if you’re using a mouse already. But it might point you to finding out the touch screen, or touch pad is confusing things.
