Can't access 'D' directories over the network in Monterey.
This problem has been mentioned before with respect to just getting a network connection. I don't have that problem. I can connect to another computer running Monterey and I can connect to one still running Mavericks. What's interesting is the three directories in my home directory that start with 'D' -- Desktop, Documents and Downloads, cannot be accessed on a Monterey computer, not from one running Monterey and not from one running Mavericks. OTOH, those directories can be accessed on the computer still running Mavericks. Sub-directories starting with 'D' seem to be okay.
