Embedded PDF problem

[PJO]

One of my uses of TiddlyWiki for some years has been to publish the agenda of an annual general meeting and a few related items in a small wiki.

Last year I switched to TW5 and embedded a couple of one page PDF files without any problem. They displayed nicely.

This year I updated the contents of the wiki and republished it. Today I got word that some pages were blank. They were certainly ok when I published them with Chrome a few weeks ago. Now, I find that they are ok with Firefox but not with either Chrome or with Internet Explorer (all latest versions). I just tried the latest TW5 (5.1.8) with the same results. 

Suggestions welcome.

Just to add to this, the embedded PDFs in last year's wiki (5.0.10-beta) no longer display in Chrome, so I assume the problem is somewhere in Chrome and not TW5. I'm using Chrome's built-in PDF viewer.

Hi PJO

PDF viewing is still a bit hit and miss on modern browsers. Do the original, unembedded PDF files display OK in Chrome and IE? I guess you're on Windows. If I understand correctly, Chrome uses its own PDF viewing engine, but you can disable it as instructed here:

Yes, the files display ok in unembedded form in both Chrome and Internet Explorer. Indeed, I'm using Windows (7). This is disappointing as it used to work nicely :-(

Will it be any different do you think if I link to a local copy of the PDF rather than embed as an attachment? (i.e., display within the tiddler).

I'd expect links to local PDFs to work correctly, yes. Not as useful as embedding, though. You might also want to experiment with embedding a linked local PDF file:

<embed src="mydocument.pdf"/>
