[Pharo-project] annoying press "ok" when running tests (not headless)

i started tests and leaved image for a while, but when i went back hoping that it already finished, i discovered that it waiting for me to press ok and did not ran even 20% of all tests. Somewhere in GoferOperationTest>>testMerge it says 'No changes' and waits for the user to press 'ok' -- Best regards, Igor Stasenko.
