Recently some customers reported an compatiblity issue between IE9 and Forefront TMG2010.
After install IE9, Microsoft Forefront Thread Management Gateway management tools cannot work anymore, it gives error message like “member not found”, “refresh failed”.
And going back to IE8 the problem was resolved. This seems localized IE9 is installed. Gernam and Russian language were reported being affected.
We are investigating this issue, the current workaround is:
Recently we have some cases that the customers reported the rendering issues with Facebook after upgrading to IE9 RTM.
In every case Facebook had been added to the Compatibility View list due to issues during the Beta or RC or IE8. Facebook does not want to be on the CV list, and we don’t want them on the CV list.
To get back to a great rendering experience, please do the following:
ALT + Tools :: Compatibility View SettingsRemove Facebook.com from the listOK
That should put Facebook back in IE9 mode.
