I am using a Logitech G9 mouse and running VMWare Workstation 6.5.3 on Vista x64. The guest OS is Win XP, and has the most current version of VMWare Tools installed. Left / right buttons and mouse wheel scrolling work fine in the guest OS, but the back / forward buttons are apparently not recognized.
I have tried installing the Logitech software inside the guest OS as well, but it still did not recognize the back / forward buttons. (I didn't really expect this to work since the guest OS doesn't actually see the mouse hardware as a Logitech G9 directly anyway.)
I vaguely remember seeing something a while back about editing the virtual machine config file to specify a 5-button mouse rather than the default 3-button setup, but I can't seem to find any specifics on how to do so in the VMWare documentation. Does anyone know if such a workaround exists, or is 5-button mouse functionality just not supported?
