If I try to save my source while POV is rendering, POV shows an hourglass
cursor and stays that way for a long time. Saving while POV is not
rendering is nearly instantaneous, and if I put my file on the local hard
drive POV does not even display an hourglass cursor.
My files are all on a server using the AFS filesystem. From what I've
heard, the Windows machines on the network use some sort of emulator to
access the AFS space. I do not have administrative priveleges, but I would
not expect that to cause this kind of problem.
The computers I'm using are Dells with 1400 MHz Pentium 4 processors,
Windows 2000, 256 MB RAM.

I experienced exactly the same here with Windows NT on VMWare when saving
to some drive on the host via smb/samba.

Well, if it doesn't crash or block, what is wrong with it? If the OS
network service doesn't have a high enough priority it will take longer
until it has processed what it is told to process. Changing the process
priority for POV-Ray will most likely eliminate this slowdown.

I agree that it's not a big deal. I can always stop my render before
saving. If there's a solution, though, it would be nice to have it fixed.

Yes, complain to the the manufacturer of the operating system and ask them
to give their network services a higher priority. The slowdown comes from
the operating system :-( There is no code in POV-Ray to intentionally slow
down saving files to remote disks if it is rendering ;-)

I don't think so, the Program should not be blocked even if saving takes
some time, changing the priority does not seem to have any influence BTW.

Well, like in all (even DOS!) operating systems a program does not see a
difference between a remote or local volume. It is completely transparent
and everything is handled by the operating system. So the program can do
nothing about network speed or handling of network transactions - it doesn't
even know it is a remote volume!

Of course, but IMO the program should not be blocked when saving on any
volume. I'm quite sure this is possible.

I am not aware of _any_ program that would not block. Do you have an
example of any such program either commercial or free?

I realize it's probably a bit problematic, because the user could change
the file after initiating saving. Anyway, at least the autosave function
should work in background, i think quite a lot of apps work this way.
