You can understand that when Apple or Google or Mozilla release new browsers and they don't work with Microsoft web sites. You can also understand when Microsoft releases a new browser and it doesn't work fully with Apple or Google web sites. But I cannot understand why Microsoft will release a browser and it not work with Microsoft web sites.
A adCenter Forum thread has complaint from Microsoft adCenter advertisers that Internet Explorer 9, Microsoft's latest browser, does not work with the adCenter Forums.
Basically, if you are using IE9 and trying to post a question in the forums, you are completely out of luck.
One advertiser said:
I recently upgraded to IE9 and have been unable to post to the Adcenter forum. It works fine with another browser. When you hit post everything you enter disappears never to be seen again.
Microsoft said they are working on a fix but until then they recommend:
Workaround is to click 'compatibility mode' (symbol next to the address link).
Also this should be fixed also in final release of IE9. But if you still can't post use the 'compatibility mode'.
