Don’t expect MS to hurry up and fix this ‘bug’. I question if it is even a ‘bug’ and not a specific design feature! That this ‘feature’ has been around so long probably means that it has been routinely exploited for years, possibly longer, to the financial benefit of the advertising agencies. More reasons, as if they were even needed, to switch away from MS and IE.
