We run the SR3 upgrade in our agency on all computers (completed successfully). After the update, verification settings (QA Checker 3.0) went back to default but PMs set them again. On one computer, however, there is a problem: we select preferred settings, close Studio, open it again, and the settings are reset and have to be set again. What is worse, the PM discovered that closing an SDLXLIFF file (not Studio) and opening another file also resets the settings. I reinstalled Studio but the problem remains. The issue was not present before the SR3 upgrade. Any ideas what causes this and how to solve this?
