Well, I upgraded to Camtasia 2018, and here are a few of the problems I am having: 1) imports from prior version projects freeze before completion or have incomplete content. 2). the video portion of a recording can't be seen on the timeline. 3) I sometimes get a crash when I unlock and then re-lock an audio track. 4) the scissors icon (for Cuts) does not work. I do have both Camtasia 9 and 2018 on one Win 7 machine...could this be an issue?
