Is there a way to make the pdf preview big?

And that does work as well with your .ini file (here):

Well, that is not working here (although the normal preview panel works).

Is Adobe (any Acrobat version, commercial or just the viewer) installed on your system?

Do you get thumbnails for pdf files? The hoverbox uses the thumbnail handler for the preview.

Which exact version is Sumatra (you did not use a preview version of it, do you)?

No. The only Adobe stuff in my system is a very old Photoshop (v7.0!) and Adobe Flash Player for Active X.

No, not in XYplorer. I do get them in Windows Explorer though, and in the XYplorer's preview pane.

v3.3.3 64bit

And you don't have _any_ thumbnail creating software installed?

FastPictureViewer, Icaros or anything else?
