Issues with wptdriver and complex pages

[auduny]

I've got a setup a two wptdriver clients (windows 8.0 64 bit norwegian) and windows 7.0. 64 bit norwegian) running on two hp elitebook 2540p laptops. The server is running Ubuntu 12.04 and most stuff works as expected.
All simple pages works flawlessly, but when we run the frontpage of http://www.vg.no/, or company site (...) it will fail most of the time. Especially with chrome. It starts but stalls after a random amount of time usually while the browser says "resolving host", it may or may not have rendered some part of the page, sometimes it runs the first view flawlessly, sometimes it even finishes, but that's rare. When it happens the client machine freezes up for several minutes.. This only happens when run from wptdriver. Surfing the same page manually with chrome works flawlessly. Any suggestions? Does wptdriver log somewhere?
