I don't know how many of you do this, but I leave Opera open all the time at work... with at least 4 windows open at all times. As long as I'm using it fairly regularly, everything is fine, but if I come into work in the morning and start to do some browsing, I'll refresh one page and then it'll hang for a little bit (10-15 sec sometimes) before giving me control of it again.
It's not that bothersome, just a tiny bit annoying. I'm just curious if it is this POS work computer and it's even shittier network or if anyone else has seen this behavior?
