Hello Chris,
I hope you had a great holiday. As for your questions, I don't know what a clipboard manager is (3rd party plug in?) so I would have to say I'm not using one.
I was able to get the file to print by combining the text boxes. The real problem with Photo is the keyboard (cut, copy, paste, return, etc.).
I have other problems with Photo and Designer. I've made saving often, and crash/restart part of my work flow. It would be nice to get that resolved, but I haven't been sending reports because I still had the first issues to deal with.
Thank you for your time.
PS: If you still need the file I'll send it, but I was able to get it to print.
