I was moving along very well, until I updated to camtasia mac 2019.0.6. I have never experienced the issues I have seen recently. I have freezing, no playback, hard to move scrubbers to edit, crashing, and non responsive. I am in the process right now of trying to finish a project and I have to keep closing down and restarting. I have sent in several of my crash reports. I have been pleased with Camtasia until now. I hope you have a fix that will be coming out soon. I really need to get my projects done. Thank you.
