These problems occur because you are not sync'ing the marks that were
cached in the agent (while unplugged) when you next plug in.  What you
have to do is press 'J Y' in the group buffer BEFORE opening a summary
buffer.

If you don't want to do the 'J Y', update to "No Gnus 0.3, Sept 21".
I just checked in the patch to always bypass the agent when writing
nntp marks.
