Fedora Hardware :: Mouse Settings Utility Is Severely Malfunctioning

I don't know whether this should be filed under hardware or laptop, but my wireless mouse is acting sluggish. At first I thought that it was because I chose LXDE as my gui and maybe its pointer was just inherently bad or something, and began to regret my decision. However, upon trying the laptop's built-in touchpad, I found it to be smooth as butter. So, the problem is with the mouse. The mouse worked fine on Windows, so the problem is with the interface between OS and mouse.

Would the problem be fixed by installing a different Desktop Environment? Or is it something else? Is there a better driver I can download or something?One last thing of note: the mouse settings utility is severely malfunctioning. I change the sensitivity and hit OK, but when I check it again, the mouse sensitivity is reset.
