    He (or she) also says the toolbar switches, which is generally a mouse operation, but he's hitting the keyboard when it happens. Again, a keyboard problem.
    Software bugs are quite versatile and chaotic and his no-scroll-wheel mouse is something that distinguishes his situation from the norm. This is a general reason to suspect there might be a connection.

    There is another more specific reason: The effect he creates with his running is something usually mapped to the scroll-wheel of the mouse (i.e. the toolbar switch)

    Usually at startup keys and mouse functions are mapped according to the config to specific keys. The scroll-wheel, being no simple on/off key might have a special routine that handles the events coming from the mouse. Now this special code was likely never tested with a PC where there was no scroll wheel.

    Examples of bugs that could happen are

    1) The scroll-wheel routine initialization code is never called but the routine itself is still called in specific circumstances and wreaks havoc then
    2) The initialization code when called with no key mapping sets it to some semi-random mapping value that coincidentally is the "W" keyboard code. So instead of no mapping there is always a mapping of the scroll-wheel function.

    This is fishing in the dark naturally, we don't have the code to refute hypothesises directly. The special routine I was talking about isn't all that likely because the scroll-wheel might as well just produce standard key-press and -release events, no need for handling it differently than keyboard. But it is a theory that fits the problem and we got no better. And the best part about this theory is that it is easy to test by just connecting a normal mouse.

    Without more and better feedback from the op we're stuck trying to help. If the computer was in front of one of us we'd just mess with the control settings or swap out the mouse and see what happens. He very specifically describes a two button mouse, then sends a picture of a three button mouse. That's not quality feedback.

    Also @Meganoth, thanks for the explanations. I noticed in the control options that the toolbar switching by default is un-mapped, yet works with the scroll wheel, and that zoom in/out is mapped to the scroll wheel. So there is some mysterious coding going on with the mouse wheel, like you said.
