  I too have been seeing this problem for some actually.  My
not-caring-enough-to-solve-the-problem method of getting around it was
to first log into the machine remove the entry from the routing table
then then start ppp.  I assumed that this was a problem unique to me...
"glad" to hear that others have simular problems.
