Studio 2021 Freelance Plus crashes when trying to edit locked segment ?

Hello, 

has anyone tried this? 

Open a file in Studio 2021 freelance plus, lock some segments. Then select some text in a locked segment, and try to change the format to "italic" (CTRL-I) . 

Studio crashes consistently in my case. Before crashing it shows a dialog, saying that locked segments cannot be edited. Which is true. But one should be able to continue after confirming this.

This looks like a bug!

I was wondering if someone else is able to reproduce this behaviour. Let me know.

Best

Jan
