I already searched, so before I get flamed, please just post the link to my answer if you have found it. Thank you.
I have a new aluminum iMac, updated OS, using a Razer Death Adder Mac edition mouse. I have installed the newest Razer drivers. The Death Adder can change track speed on the fly. Upon installation, I set the standard Mac mouse track speed (System Preferences) to two notches from the fastest, adjusted the Razer settings, then while using I just adjust the mouse on the fly. It works great while in use; however, when the computer awakes after sleeping the standard mouse track speed settings have been reset to a much slower setting. It does this each time it sleeps. I have to fix the System Preferences settings each time I use the computer. Is there a way to fix this? Anyone else having this problem? Thank you for your time.
