I loaded V:16 from V:12 which I'd stuck with because it pretty much worked OK.
I've had nothing but trouble ever since, the system has become intolerably slow, machines lock up and hang even when doing relatively simple tasks etc etc
We have had the usual round of,
its your network, its your server, its your machines
etc etc. So to date we've:-
1) Upgraded our network to 1GB speed
2) Changed my machine to a higher spec model
3) Had our software and hardware support people in on numerous occasions
4) Installed all avaialble upgrades (we are currently at v16.017.0156
Cost? no less than £1500 so far to date
Outcome?
Its still as shonky as hell !
It is not your fault, its not your kit, it is the software!
(Incidentally, I'd love to be proven wrong on this, as it means there is a solution available, so if anyone wants to prove me wrong please please do so.)
