When I try to open a PDF, it opens a new Preview pane window. I can't figure out how to open it in the system app (Foxit). I searched a bunch online and tried AI tools, but nothing works.
Windows 11, Opus version 12.
EDIT:
I don't seem to have this problem with doc, docx, txt, ppt, etc. But image files are opening in the viewer pane. So then I toggled the "Use internal picture viewer" option in Preferences > File Operations > Double-click on files. With that off, it opens the PDF in Foxit. But it still asks every time which app to use, even if I select "always". This is a bit annoying but I suppose good enough for now. If anyone has a better way to fix this so it's more natural, I'm all ears.
