I'm always late on these threads. Jeez.

Anyway, just though I'd drop my two cents.

A few months ago I upgraded to NAV 2003, and my machine began to ran slow. Turns out, like I believe was stated earlier that NAV can be a resource hog, and it is indeed sometimes. I disbaled auto-protect in the systray and everything was fine. So just something you could try if you want.
