Hi. I'm wondering if anyone could help me. I have a A4 X-748K mouse which I am having problems with. When playing games I cannot map custom controls to the 4th and 5th buttons. Instead it maps it to the "left Alt" button when those buttons are depressed. The buttons work as expected when using windows explorer and internet browsers (back/forward) which is frustrating as it means it is not simply a hardware malfunction. I have tried to use the X-Mouse button control program but that doesn't recognise the keys. I have the driver and the program that came with the mouse (Oscar Editor) up to date. I have searched for any similar cases and found only one which was resolved by launching the games in administrator mode. This, unfortunately, did not work for me. Anybody got some advice? It would be greatly appreciated.
