I've started having problems viewing the forum when using Chrome (currently on 45.0.2454.93 m running on Windows 10). Pages will freeze and they will not scroll down, the page loading 'spinny thing' in the tab keeps spinning, it looks like it is related to the ad carousel as I have a similar problem on another site I visit which is related to ads. If I open the link in a new window it all works ok, in a new tab not so good. IMO it could be one of two things, Chrome doesn't like the ads or it sin't playing nice with Windows 10.
I've moved to browsing here using Firefox and that seems to work (suppose I should try Edge for completeness). IIRC Chrome have changee how they handle Flash or Shockwave so it could be choking on that or it is some combination of Chrome and Win 10.
