We have been working some customers who are experiencing some weirdness trying to get dual monitors to work on Dual Core CS's.  Basically, the problem is that the Windows desktop will not extend to the second monitor, the settings are not saved on restart, and nothing done in the Display Properties fixes it.  

The reason is the video card.  This has been confirmed by Patrick.  For about the last month or so, we have been using a similar (but slightly different) MSI video card.  Both are red and have gold heat sinks.  The new one has an angled cutaway on the card while the original is a solid rectangle.  Mikey's computer has the original in it.

There is no current solution, but we are working on getting either new cards or a firmware update to fix this.  Ask Patrick if the issue comes up.
