There was a problem with one of CRCs flash adds a while back that was making them much more processor hungry than they needed to be, and on being notfied they replaced them with ads that looked identical but were beter behaved and i'm wondering whether its the same issue with the current ones. I think the culprit had animated parallaxing snowflakes. The parallaxing text on the current add is stuttering for me just now
The adds pay for the site and I have absolutely no problem with that, but they shouldn't compromise the site, thats counterproductive for everyone.
My lappy is crawling with the site as it is just now to the extent that typing this is pretty laboured, and battery life is minimal. My thighs are nice and warm though. With the ad I had to complain about you could actually hear whether its was on the screen or not.
