I also have a similar issue. I have been trying for an hour now and I can't download anything from Opera. The download feature takes a long time on the timer and then just stops. Sometimes it does nothing at all, sometimes I manage to get a fraction of the file. I have tried using IE, FF and Opera Next.
Incudentally, why has my Opera browser stayed on version 15, when we are now on at least version 18? Why haven't I seen a seen a single update in a year?
