Indispensable little plugnin - makes following through on notorious non-responders so much easier :-)

Great virtualization software, and totally FREE! Not quite as feature rich as Parallels or Fusion, but subjectively faster that Parallels, and with most features that average users need like the seemless mode to mix Mac and Windows applications, folder sharing, networking, USB device support and the ability to save the last state for faster start-up.

Not everything in the interface is intuitive, and for some things like how to access shared folders in the guest OS one needs to ask the help function.

But then, it's free, fast and for me also stable. A great way to run Windows on a Mac for occasional use.
