or in Windows 7/10 x64

Set the value to Remote and restart your connection

I am running Synergy.

It seems that there are issues with how it hooks 'special' keys and it keeps them local rather than allowing them to happen at the remote site.

As a bodge round I now have a small script that stops and restarts the synergy services which seems to work round it for 'a bit' (about an hour).
