John, thanks for taking the time to address this. I don’t have any URLs to provide right now, but I have seen several annoying ads that block the content with full motion video and Flash.
I see them a lot less than I used to because I use the FlashBlock plugin for Firefox, due to a bug in Firefox on OS X.
I’m not sure what, if anything, Macromedia can do about this. If there was a way to prevent Flash content from displaying on top of HTML content, that would probably address the problem. I don’t do any Flash coding though, so I don’t know what wider implications that would have.
