I'm all for using ad/popup blockers and such myself guys. But I guess the point I would make is that in a case like this having something like this simply "mask" an underlying problem. And since it is not necessarily so unusal that people coming here would not have the latest greatest flash plugin (since IE comes with V5 by default) proper viewing of the site pages really shouldn't be dependent on such a thing. Pages at a place like a VDR really should be as "browser friendly" as possible.
