I've been trying to buy ads on MSN with the new adCenter, and it's incredibly flaky. I have to open Internet Explorer, of course. But even in IE it has a million little script errors, missing css/xml files, etc. The stuff just doesn't work.
Sometimes the interface doesn't show my ads, sometimes it takes forever to show my keywords. AGGGH!
OTOH, it's the closest web interface I've used that simulates what it was like to use Windows NT. When you have a problem, you just reboot - or in this case, restart the browser, login again and hope.
If anyone has tips for how to reliably use MSN adCenter, please tell me!
