If you're a serious Linux user, and all engineers should be, you need the middle click. Synaptics makes it really hard to get. I had this solution scrounged from the interwebs. Save the following text to synaptics_middle_click.reg and double click it.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Defaults]

"HasBothButtonFeature"=dword:00000001
"ButtonModePlugInID"="SynTP"
"ButtonModePlugInActionID"=dword:00000027
