1) probably just click somewhere outside of the popup menu.
2) possibly click in the lower right where the check mark and x mark usually are.
3) Otherwise the program may be frozen, so you may have to force-quit videoscribe.

Thanks for getting in touch.
This looks like a old beta version.
I would advise downloading and using an official version of VideoScribe.
Thank you @Mike Metcalf for answering my question, but I did force to shut down the program and thanks God it can be recovered after reopening it.
And @Joe Clarke could you please tell me where can I download the new version?
