The only mistake the previous commenter made was understating the lousiness of ScreenFlow support. ScreenFlow support, upgrades, etc are all absolutely r-i-d-i-c-u-l-o-u-s. I continually get the same error as the previous commenter which goes way beyond the classification of "bug". This so called "error" renders the entire application completely useless! And then to waste what minimal support advice they offer to simply "pass the buck" off on a handful of other applications you might be running is pathetic.

During the advent of ScreenFlow, potential was it's most rousing asset. Since then ScreenFlow hasn't made any compelling advancements at all.

Add it all up and it's easy to see that ScreenFlow is a total bust. Save your time and money and check out worthy alternatives with better support and less arrogance to think that users are going to overhaul their systems just to be able to run ScreenBlow.
