Thanks for your hard work on this engine. I used it before the update to qualtrics successfully. Since the issue, I’ve gone back to using version 15, which seems to work okay. However, the one problem is that my stimuli is no longer aligned vertically on the browser. It used to be centered in the middle of the screen; however, it only centers horizontally, not vertically now. I really do not think I changed the code at all from the previous times I ran this study, so I can’t figure out what could be causing this. Any thoughts?
