I am fairly confident I could use the service below in MRD before. I am not sure when I lost them, maybe it is related to the Yosemite upgrade (I noticed this on 10.10.0) or some recent MRD update (8.0.9 from Mac App Store). In any case, the Services menu (from the app's menu on the menu bar) lists the services I want to use, but all are greyed out an inaccessible. Why is that? Can one undo this?
I checked the services under the Keyboard preference pane, and they are enabled. They also work in other apps.
It is not related to any restriction on any specific RDP connection, even without connecting, the services are unavailable.
The services is simply an automator workflow left under
~/Library/Services, with running AppleScript:
repeat with theItem in (the clipboard)
tell application "System Events" to keystroke theItem
