Recently (everything has been fine until a few weeks ago) I've started to
have this problem with two XP Home computers running through a router and
with McAfee Personal Firewall on both PCs.
The problem is, when placing files in some sub-folders in the shared
documents on one computer, they have 'disappeared' on the other computer.
It's the same case if the other computer places a file in a sub-folder of its
shared documents. The strange thing is, is that this is only happening with
some sub-folders (though recreating them has no effect). Though the files are
guaranteed to appear on the other computer if they are placed in the root of
the shared documents folder.
So what's going on?
