Have installed this software and quite happy with it. It is an application for the users who use multiple displays so I tried a couple of years ago on C521 but there was a conflict with motherboard. Now it seems working fine and I can use the task bar through 4 monitors. This feature is pretty much handy and it can save heaps of effort to find the applocation tabs on the task bar.
Another interesting feature is that I can set the different wall papers and screen savers on each monitors.
