In de reacties kwam ik dit tegen:
Dit is misschien nuttig om weten...For security reasons, we use Mozilla and FireFox exclusively. We have also set our firewall up to forbid IE from contacting anything on the web without obtaining explicit operator permission.
We have encountered only a very few sites where the implementers were dumb enough to use nonstandard, IE-only features to present their vital company data to the world.
In these cases, we have found that an e-mail to the MARKETING department will almost always produce a "cure" within a week...sometimes much faster. Don't waste time writing to the web technical support folks: they caused the problem, and probably won't understand that their site is defective. Their own marketing and/or management folks will remind them who they are working for (not Microsoft) and what the web site is for.
After all, who wants to pay to publish an advertisement which cannot be read?
