We have a Windows Server 2008 R2 with Remote Desktop in "Per User" licensing mode.
User goes to Remote Desktop Web Access and starts Exel 2010 as RemoteApp on this server.
User then clicks on items in the ribbon that display a drop down menu (for example "Sort & Filter") or right-clicks in a cell. Many times the menu is briefly displayed and then immediately disappears again, making it impossible to use. The problem occurs with Word 2010 as well. The problem is more likely occur if the user has multiple RemoteApps started in the same session.
This problem does not occur in regular Remote Desktop sessions to the same server.
When we got reports of this from users on Windows 7 SP1 we suspected the KB2592687 update, and sure enough, when we uninstalled this update the problem no longer occurs. We then also noticed our Windows 8 users have the same problem.
There appears to be a severe incompatibility between an RDP 8.0 client and an RDP 7.1 server when using RemoteApp.
Has anyone else noticed this problem and is there a workaround other than upgrading our server to Windows Server 2012?
