What is the best way to do that? csupping to "." seems a bit drastic, and I don't do much with cvs proper. I take it that I should use anon-cvs to grab the directory, but I don't quite know how. > >This is possibly a bit left field - but I experienced something like >this once, and it was due to overheating - the edges of the (large) cpu >heatsink hung over the circuitry concerned, preventing enough airflow >and obviously offloading heat!

Mind you, North Queensland could do with some cooling! I will take another look at the circuitry if moving to HEAD's re doesn't fix it.
