Delete or hide Refresh icon ONLY, but keep Seekbar

With the way my course is setup and with everything I've read here in the forums, the refresh button that comes with the seekbar simply won't work.  Most of my slides are set to "resume saved state" and have multiple buttons and triggers based off of the learner doing something.  I also need the seekbar visible so learners can rewind narration as needed.

All I want to do is hide the refresh button so that it's not confusing to learners - it's just a dead button with absolutely no purpose.  Anyone have any ideas on how I can do this?
