The problem might not be specific for OI version, but it still happens in this OI release.
When having "PDF Viewer" or "PDF Viewer for Vista" activated in ActiveX plugin scrolling with the mouse wheel does not display of all pages of a multi page PDF. Normal scrolling does work well. But when you used the mouse wheel one time all the following pages of the PDF will be empty no matter how you scroll the pages.

That's one of the reasons those viewers are disabled by default (and it should warn you if you enable them). It should be dropping through to IE and using Adobe Reader (or Foxit, etc. if you have alternative PDF viewers installed) rather than the preview handler for PDF.
Or were they not disabled by default for you? Maybe my code isn't detecting it in all cases.
This warning is mean to appear if the Adobe PDF preview handler is turned on:
Afaik it is disabled by default and it displays the message you mentioned but due to this message I would not expect such problems.
So maybe the warning should be more detailed (is there a reason for this option?) or it should state that you do not recommand its usage.
Isn't the current warning enough of a dis-recommendation?
I don't want to remove the option to enable it completely as it's possible Adobe will improve their preview handler in the future. It's also possible that someone's Adobe Reader (etc.) may be broken and enabling the preview handler is better than nothing.
No, I don't think so. I would generally recommand to disable it if the user does not have a good reason to enable it.
I have foxit installed but do not see Foxit Preview Handler as an available option. I have dopus 9.1.3.0
The FoxIt preview handler is a separate thing you can install in addition to the main FoxIt program.
You shouldn't normally need to install the preview handler to use FoxIt within Opus, since FoxIt should install itself as the PDF handler which Internet Explorer uses (and Opus views PDF files via IE by default).
If something else has taken over PDF in IE, you should be able to get FoxIt back by reinstalling FoxIt over the top of itself.
Still, if that doesn't work then the preview handler should work (and will also let you use FoxIt to view PDFs in Vista's Explorer and Office 2007).
Thanks Leo.
only downside of the Foxit Preview Handler is the banner across the top that takes up a lot of screen real estate.
Am on the eternal quest to get PDFs to load as quickly as possible in opus.
If you get FoxIt working in IE then you don't need the preview handler and won't see the banner, FWIW.
they load in dopus with foxit and IE. I guess it is the IE part that slows things down. Am using firefox. Is there a way to substitute firefox for IE?
back in the good old days of previous dopus versions about 2 years ago, pdf previews opened very quickly, now they take about 10 to 15 seconds to load.
Firefox doesn't provide a way to use it within other programs so it can't be used instead of IE. I doubt it's the IE part that's slow anyway (unless your IE install is messed up, maybe).
Do you know what you used to display PDF previews in Opus in the past? It could have been Adobe Reader (which opens pretty fast for me these days, though some versions were very slow) or it could've been the MultiView plugin which uses the QuickViewPlus-style viewers (if you have them installed).
I used adobe in the past and then switched to foxit.
any suggestions on how could i check the IE install? i currently have ie 7
Not sure about the plugin. How do i install the MultiView plugin which uses the QuickViewPlus-style viewers?
Try viewing a simple HTML file in the Opus viewer. (I've attached a zip containing a good, simple test HTML file that doesn't download any external files.) If it takes more than a second for IE to load then something's probably wrong.
To be honest, I wouldn't bother with MultiView for PDF files, as tracking down the right 3rd party viewer DLLs can be a pain and it should be possible to make Adobe Reader or FoxIt work well in Opus without using MultiView. If you want to, though, this thread is the best starting point.
