Record button disappears

Every once in a while i get a communication dropout but when this happens the video stops recording and the record button disappears. I have to shut down QGC and start it up again to get the record button to appear again.
I still can’t find the cause of the dropout but it is the disappearance of button that causes me the most problem. Has anyone had this happen to them and is there a software fix for the button disappearing.

What version of QGC are you using? This should be resolved in our latest.

@jwalser Yeah had rev3 and not rev4. Didn’t even notice update. Thanks
