I am currently trying to use the drop down in Lectora to select a variable to change a text box too. However, every time I click the drop down, my Lectora Locks up. Please view the attached Video and Photos
Are you planning to upgrade to v17.1.3? I’ve recently upgraded from 17.1.1 to 17.1.3 (to fix some publishing errors), and I just tried what you were doing in the video, and there were no issues, I was able to open the Text dialog.
