Razer Lachesis 5600 dpi issues

Hi all, I'm a new poster so sorry if I'm leaving anything out here...

A couple days ago, I bought a Razer lachesis 5600dpi mouse. I love it, except for one issue:

Whenever I use the "adjust sensitivity" button (up or down) or if I use a macro button, my keyboard seems to stop working and my desktop seems to act as if ctrl is held down (icons will stay highlighted even if I try to click off of them) and programs will act weird (for example, firefox will try to open in safe mode when I click on the taskbar icon). Stopping the application that starts with the program to customize mouse buttons and all that doesn't fix the problem, nor does using a different keyboard, a different mouse (once the problem has started), or unplugging and plugging the mouse back in. I just e-mailed the razer support team and am waiting on a response from them.

Has anyone ever heard of a problem like this with a razer mouse or any mouse? I'm new in the realm of gaming mice (this is my first one) so I'm kind of disappointed that I'm having problems. If you guys haven't, do you know of anywhere else I could go to find some answers? If I come across any more problems, I will repost.

Thanks.

 

Oh, and I'm running Windows 7 64-bit.

 

Hopefully they get back to you soon. Have you checked the mouse's webpage to ensure you have the latest 64-bit driver for Windows 7?
