I have XP installed as a guest OS on two machines. A MacMini and a MacBook, both with 1GB of RAM.
On both, I'm having problems with shared folders which are seen as network drives by the guest OS, XP.
Just now I tried transferring a 266MB file from a shared folder to the XP desktop. The transfer has hung every time I try to move or copy the file across. I've seen this problem on both machines.
On one of the machines, XP will not shutdown smoothly, hanging on each occasion at the point where it's disconnecting network connections. After deleting the shared folders from the shared folder panel, XP starts and shuts down without problems.
