Every time I log into Flickr it takes an absolute age for my pohotos to appear - if they appear at all. Has anyone come across this before and is it a conflict with McAfee?
Could be that McAfee is doing some scanning here. This is a site-specific problem and I haven't yet seen anything elsewhere that would throw light on it.
One thing that might have an impact is if you have any of the coonections set up as in this screenshot
