Yes, that definitely is possible, but if that was the case the Window>Workspace> menu would say "Reset Laura's workspace".
I think it's more possible that your workspace got lost in an update, I fear.
You didn't post a SINGLE photo in class. I sure hope you're not telling people "I took Damien's Raw Class but it didn't help me". Of COURSE it didn't help you, you didn't post any photos.
Take the damn class again, and USE IT THIS TIME.
