There's a strange issue with Vegas Pro 19 (Steam Edition) and its Credit Roll generator, where the whole program just freezes while switching languages (Shift + Alt or Win + Spacebar) inside of the Credit Roll window. There are no errors, and the program doesn't get the "Not Responding" status, however I can't close the window or click anything.
Apparently, you have to be editing the text for it to happen.
Essentially, the program gets frozen in this state.
