hey yassim, my workplace does that as well. I usually circumvent that by adding 'cache:' in front of the web address to pull the google cache (This might only be applicable on Google chrome, though)
yea, this happens to me all the time. Ed Weissman's solution to this is to have a separate work station (qn 64, http://edweissman.com/53640595).
Personally, I open separate browsers for work and general surfing (email, HN, twitter etc). For instance, all my tabs for work will be on Firefox (tab groups and tab mix plus work wonders for tabs organization BTW) while all other non-work related surfing will be done on Chrome.
I think nobody and spot may have been referring to pension funds as well, seeing that many pension funds did have the AAA rated CDOs in their portfolios.
