This morning, I logged in, then wrote a reply on Jet Blast and pressed submit - took about 10 mins max.
Yet, when I pressed submit, it said I wasn't logged in - it had logged me out in just 10 mins.
Could it be my iPad doing something odd, or my Wi-Fi ?
Pprune is a pretty good site from a user point of view, but it would be nice to find the reason - other websites viewed on the same device don't keep dropping my log-in.
