weird. can you paste in a screenshot? it's definitely a problem with one of the ads... i hate ads :(
PreloadHandler?

Thanks for your quick reply Erik.
To be honest I'm not sure how to paste in a screenshot! I've been playing with the 'Grab' utility on my Mac to try to get one for you but it doesn't want to drag and drop to this message, sorry my lack of knowledge here doesn't help.
I've tried to keep a note of the ads that cause problems - but there are quite a few. I don't get the 'PreloadHandler' message on every page of the site but I've noticed that the Mike Rowe Ford ad, the Avis ad and the Pogo ad always cause it. There are others too.
I wonder if this post is a related problem?

Thanks again
What is it?
When I try to navigate around chess.com my Mac attempts to download a doc called "PreloadHandler.ashx" then - "PreloadHandler-1.ashx" etc, I get at least ten of these docs on every visit to the site. I've used the site for over a year and yesterday was the first time this has happened. What gives?
