Media Player Classic and middle mouse button issue
I have a windows 7 and whenever I play anything on Windows Media Player Classic, the middle mouse button does not work as a vertical scroll in my web browser (firefox), but instead shows a horizontal scroll but does not scroll the web pages. How can I fix this problem?
I hope that was clear.

Try installing (and updating) the driver from the mouse manufacturer's website.
i just found out that the issue happens when I press the middle button of the touchpad only, while it works fine in a mouse middle button. And I only just noticed that I said "mouse" in the original post instead of touchpad...my bad
Did you try updating the touchpad driver? (as you are aware, this is different from the mouse driver).
