Not yet. I was hoping I would be able to solve this myself. But I’ll see if it works by having someone make a minor change. Thanks!
This has happened to me about 3-4 times now. A bit of a trouble to send it to someone else each time. Just now I found something that is working for me: move the .psyexp out of its folder, quit psychopy, open that file outside of its folder (where the tabs reappear), then Save As back into its original folder.
Hope this helps
