XYplorer Beta Club

They are all set to 0 in my config but I get the small pdf preview as well (with PDF XChange Editor).

Really?! That's MDBU, right, not Hover Box?

Yes, MDBU on icon in Details View.

In the next beta (v20.80.0101), do this: or select the PDF file in the list and do this:

Probably not what you expected:
but looking like this:

Well, it's a first step into knowledge...

PS: What about your Hover Box on PDFs. Also small?

PS2: Should be fixed in v20.80.0102.

Yes, hover box for PDF's was small too.

Unfortunately not there yet, 20.80.0102 results in a "Cannot decode" message for the same PDF as above.

Oh.

Something must be wrong with your shell extensions (thumbnail handler in this case). Are you sure PDF XChange Editor is correctly installed?

I had an older version (7.xxx) of PDF XChange Editor so uninstalled that one and reinstalled the newest version 8.336 but still no luck, same message of "Cannot decode".
And I haven't got any special codecs installed ether.

Following your Shell Extensions reminder, I finally dove into that after following a reference I came across about User-Defined Preview Handlers. Found the Sumatra handler and added that. There were two entries with the same GUID (in ShellEx). A thumbnail and preview handler. In my case I get neither a thumbnail nor MDBU preview with that GUID configured in XYplorer as a custom handler for PDF's.

Just sharing - as I try different things, I too see the tiny MDBU preview if I have the PDF-X v8 "Editor" installed but the preview was the expected size when using the v2.5 viewer - https://www.tracker-software.com/produc ... scontinued. But I think I discern from the discussion you've already got a handle on that issue in the current beta.

Yup, MDBU size fixed in the beta but some PDF's still get Can't Decode and as such get no preview.

Well, not fixed for me, as I haven't found a pdf yet that doesn't show the "Can't decode" message.

Weird. I wonder why not more users a re reporting that the last beta stopped working for PDFs.

Apparently, neither the GUID's nor the names seem to match - for whatever reason.

Here again my installed version PDF XChange Editor:
