Hello,
This issue is similar to my earlier post here: https://forum.affinity.serif.com/index.php?/topic/26841-cant-export-single-artboard-instead-of-whole-document/
So please either delete, mark as duplicate, etc. if it has already been addressed and fixed.
Whenever I go into Export Persona mode the right panel just disappears and I can't click on anything. Even if I go back to Draw Persona, I still can't do anything. I essentially have to restart Designer if I want to be able to work. However, while in Export Persona, if I click and drag I can see the right panel highlights changing. You can see this in the screenshots I attached.
I'm on Mac 10.8.5.
Thanks for any help,
-Jeremy
