Hi, A program I use daily at work Peachtree Complete Accounting stores its data files on our network server. Under Parallels 3.0 I had no problem accessing the files and using them in Peachtree. However, now that I've upgraded to 4.0, the data files are visible in Windows Explorer, but the program Peachtree cannot open them. It says "Cannot open file 'f:\...'. If I copy the file to my Windows desktop it opens just fine. It's something over the network preventing it. I had it set to map folders to Windows drives, then I mapped the network folder myself. Neither technique is working. Does anyone know what networking changed between 3.0 and 4.0 that might cause this issue?
