I have a strange behavior of Office 2013 in a Remote Desktop Session on a Server 2008 R2 which is reproducible on many other servers.
RDS role with Desktop Experience
While editing a Word document the cursor freezes after approximately one minute of inactivity.
No text can be marked or inserted. The cursor can only be moved again after scrolling or after minimizing and maximizing the window.
After that the text appears which has been entered during the freeze or the text is being marked.
RDS Role w/o Desktop Experience
Office behaves normally
If Desktop Experience is being disabled later, the problem remains
