Another small update to 1.66

Jason Neuswanger Wednesday May 25, 2016
This update includes just minor but useful bug fixes. The annoying starting position of the floating synced-playback control panel has been fixed (it should now start in the top left corner of the screen as intended). More importantly, a recently introduced bug that was causing the program to hang for 2 to 15 seconds or so during certain tasks in certain videos has been fixed. These include resizing videos, calculating calibrations, and sometimes measuring points.
