Eric,
I know, if you could, you would sort the problem for me, so don't you go worrying yourself over it.
I have tried it on IE8 (which is garbage) but still the problem persists, and I have even tried an earlier version of Firefox, to no avail.
At the moment it isn't too bad, about half a dozen clicks and maybe get somewhere, but I just can't trust it enough to do a largish post.
Ade V, the computerised whizzkid, is calling tomorrow, maybe he will be able to trace the problem for me.
I am also sure that it is not the site, but somewhere in between.
John
