OT Train Guy
this is kind of old, but i didn't notice earlier ....
I've been trying to come up with a solution that doesn't totally disable flash ...
i think the one solution that fits your problem - though maybe not what you're looking for - would be to switch to mozilla or a mozilla based browser (new netscape, mozilla, phoenix, etc.) and apply the "fix" in the link i provided: it specifically looks for things that look like flash ad's and omits them, but does not omit all flash. (i.e. just appropriately shaped/placed ones).
sigh. software is infinitely configurable, but most vendors don't expose all of those options to the user.
