Remote video causes cursor to freeze

I run a headless mini as a media / time machine server. Prior to Mavericks I had no problems controlling the mini from my 2012 retina macbook pro. When running video on the remote mini ARD (and screen sharing) control of the cursor on the remote device becomes unresponsive.
This has now been a problem for many months - even with the latest update to 3.7.2 of ARD and Mavericks 10.9.2 running on both machines.
Has severely limited the usefulness of the application.
