I have a Logitech MX300 mouse. It has a little extra button on there that you can set for various things. I have been using it as minamize all. Now it changes to "back" just a little while after i set it to minamize all. If I just open the mouse settings in the control panel then it will set it back to min. all like I want it, but I have to keep doing that all day, which is really annoying. Anyway, do you guys know anything that could fix this. I did buy the mouse refurbished, which I'm sure has something to do with it. I bought 2 refurbished ones at one time for me and my brother, and my brother's is still working like it should.
