Interesting. I”ve had no problem with the plugins (under PS CC) under HS; they work well, save for one situation. If they are used on smart objects (so in theory they changes remain live and can be edited), they crash PS when I attempt to reopen them for re-editing.
I don’t know what the change was because I haven’t been using them for many months when they started crashing as soon as I launched them. For what it’s worth I use Photoshop Elements 15. There have been several system upgrades during that time, and I assume one of them fixed that problem.
