4.3.4 on Java (linux). However you can upload the pdf to your online webstart demo (http://res.icesoft.org/demo/jws/icepdf.jnlp) and it has the same issue (I'll have to supply a different pdf that is checked- the one I attached is not pre-checked). Because of this, I haven't upgraded ICE to solve the issue but I will if you think it will resolve it.

I've looked into the encoding of annotations that make up the check boxes and radio buttons. The check boxes are using ZapfDingbats for the checks. You will need to install or stage the dingbats.pfb font from http://svn.ghostscript.com/ghostscript/trunk/urw-fonts/ on your Linux system.

The FontManager class will scan the following locations on a linux system for available fonts.
"/etc/fonts/",
System.getProperty("user.home") + "/.fonts/",
"/system/etc/fonts/",
"/usr/lib/X11/fonts",
"/usr/share/a2ps/afm/",
"/usr/share/enscript/afm/",
"/usr/share/fonts/local/",
"/usr/share/fonts/truetype/",
"/usr/share/fonts/truetype/freefont/",
"/usr/share/fonts/truetype/msttcorefonts/",
"/usr/share/fonts/Type1/",
"/usr/share/fonts/type1/gsfonts/",
"/usr/share/fonts/X11/Type1/",
"/usr/share/ghostscript/fonts/",
"/usr/share/groff/1.18.1/font/devps/",
"/usr/share/groff/1.18.1/font/devps/generate/",
"/usr/share/libwmf/fonts/",
"/usr/share/ogonkify/afm/",
"/usr/X11R6/lib/X11/fonts/",
"/var/lib/defoma/gs.d/dirs/fonts/",

If you are using the Viewer RI or the FontPropertiesManager you will need to delete the ~/.icesoft/icepdf-viewer/pdfviewerfontcache.properties so that a new one can be created on the next run of the application.

On a site note our 5.1 development work will bring forms support allowing your sample files forms to be dynamically toggled with the mouse.

We keep all of our fonts in the same directory as the app for security reasons. Any chance I can add to your FontManager where to look?

I should have looked at the API. I think this might work:
FontManager.getInstance().readSystemFonts(String[] extraPaths);

That's the call and it's also possible to load fonts from a jar if needed.
