Dear Eric

Thanks for the hint. tv=local is MUCH better - in fact I can see no subjective
difference from the performance under RH9, at least in a few minutes playing
around. [My machine is a Dell 1.7GHz laptop].

On some of the newer machines at Jodrell Bank, there is apparently a problem
with the TV "slowing up" after some number of operations. I'll watch out for
this and let you know if anything similar happens to me.

So far so good.

Thanks again.

Robert
