I'm on Mac OSX 10.8.5. Some questions not covered in the release notes:
The frame rate is fixed in version 2 of VideoScribe.
If that is a problem for you then you could raise this in the Ideas and feature requests section.
cut, copy, paste and delete are available when you have one or more elements selected. For more details see the Tutorials
Blackboard is a reference to one of the new paper textures which you can combine with a grey colour. There are hands with chalk instead of a pen which complete the look of a blackboard.
Preposterous. Utterly unbelievable.
I am also having this problem - except for 'cut' the other editing tools do not work.
