Actually, I've had several friends in the last 10 days or so who have had that same problem with really slow loads. In an alt shot game it maddening as the other three sit and watch the slow-loader circle the drain. Just about the time everyone is getting ready to say to hell with it, up he pops.
They've all tried clearing their flash cache, Skype history, temp internet files etc, to no avail. One even called his ISP and complained about his slow bandwidth and replaced his cable modem...still no solution. A clean install of the browser helped (as well as trying different browsers with the same slow loading results), but here's to hoping that doesn't become necessary more than once every couple months or so unless something else is identified as a better solution.
