I actually find Resolve better to use than Vegas Pro.
So that was why I moved to Resolve. The desktop pop up advert did impact my decision but it was not the prime reason.
Thanks for the clarification. Even between Pinnacle Studio and Vegas I find some functionality more intuitive on the former, but the instability and other absent features make me prefer the latter.
This is common all around with software - part of why competition is a nice thing.
