Ah don't get me wrong I have put in a technical support query to try and get it sorted for others that may have the same issues. I have tried the latest drivers thanks and they were of no help unfortunately. Even though I set the programmable buttons to forward and back (internet keys) after installing drivers, the game did not even notice tha buttons when depressed. As default before installing drivers they were button 4 and 5 that also had the forward and back internet functionality.
I would look further into the issue but that is only one of several problems. I cannot understand how pressing buttons 1 and 2 will then stop activation of buttons 4 and 5 on a gaming mouse however. This happens both in game and on the desktop and all buttons work fine individually, sadly this renders it useless for my purposes. Add into that the fact that when you hold down buttons 1 and 2 for anything more than a second and it changes from one dpi setting to another (which is another thing I tend to use alot) and really the mouse is nothing more than bin fodder.
I will see what comes of my report and post back if anything useful comes out of it. New Razer on order, should have stuck with what I trusted in the first place and not been so tight. I have always liked Gigabyte products and used to swear by the motherboards but maybe I was wrong to believe they can make peripherals.
