I was able to install XP Pro with Parallels 6. It is a nice step-up from v4. The database program, that is networked, works fine. I just have to make sure the Mac is connected to the network data disk first.

The only problem I have on the PC side is that when printing from a Sharp MX-2700 (PC only printer!), it prints in the wrong orientation. I still have to work on that. I use GimpPrint and it works on the Mac side, but it is only grayscale without any options. I need to use the printer's options such as color, staples, etc. I had Office 2007 installed on the PC side to print the documents...I like the Mac version better.
