Logitech Mx518 and Guild Wars

Hi everyone, I'm new to this forum and to guild wars. I was wondering if anyone has the Mx518 Logitech mouse. Guild wars does not recognize all 8 buttons and I'm pretty sure it is possilbe to use them. Does anyone have the Mx518 and have they gotten all the buttons working in Guild Wars?

Thanks

i've got the mx1000 and it works fine for me. havent tried all the buttons yet though.

I have the MX700 and it doesn't work with my extra buttons.
