I, too, see this all the time, and have since I upgraded to 3.0 (same machine, have upgraded incrementally to 3.1, 3.2, 3.3, 4.0, 4.1, 4.2 (all -STABLEs)), and have seen this the whole time. Never tracked it down, either... (Just another data point) My machine: PII/266, 128MB memory, P2L97 motherboard (everything else has changed at one time or another) --David Bushong On Sat, Mar 10, 2001 at 05:27:22AM -0800, Mike Harding wrote: > > I have seen this behavior a number of times over the years, but never > tracked it down.
