Hi Nermander,
Thanks for taking the time to look it up. However, when I looked up the 14 standard pdf fonts i found:
The font files that may be embedded are based on widely used standard digital font formats: Type 1
Fourteen typefaces, known as the standard 14 fonts, have a special significance in PDF documents:
Times (v3) (in regular, italic, bold, and bold italic)
Courier (in regular, oblique, bold and bold oblique)
Helvetica (v3) (in regular, oblique, bold and bold oblique)
Symbol
Zapf Dingbats
These fonts are sometimes called the base fourteen fonts.[57] These fonts, or suitable substitute fonts with the same metrics, must always be available in all PDF readers and so need not be embedded in a PDF.[58] PDF viewers must know about the metrics of these fonts.
I was careful to use only Times and Helvetica. Also when I opened a blank document and just put down a hyperlink box without any text at all, I still got the error message.
I think it must be some other reason or just a bug. I just need to know if my pdf document is going to be OK and I can safely ignore this error message.
