This is really two bugs in one:

1) Netscape composer crashes immediately if you try to insert a link.
No warning no message, happens every time.  I have netscape-communicator-4.7-1.1

2) It seems that I loose my ppp connection way more than I should (more
than Windows machines using same line do).  It seems to happen when I am
trying to send an email from Netscape, but it isnt clear.  The /var/log/messages
contains the following lines regularly that might indicate something:

Dec 14 22:43:08 volcan modprobe: can't locate module char-major-108
Dec 14 22:42:37 volcan pppd[8536]: Terminating on signal 15.

The second seems to be saying there are problems on the other end, but as
I said it happens much more on my machine than any other.

I am running ppp-2.3.10-3

Thanks,
David
