CafeTran's QA hasn't been working for the past two weeks or so. I only get the "QA completed successfully" popup even when there are obvious issues like extra leading spaces or end punctuation differences.
I tested this by clicking each QA item after changing the text so that there are several issues that should be spotted. I'm mostly translating Trados packages in case that makes any difference.
You may try to activate "QA for checked segments" option in Preferences > QA tab.
Thanks Igor, checking that box and restarting CT seemed to help. I wonder how that got unchecked in the first place.
