Q: Problems with making clickable linkt to web in beamer I have (on windows with latest miktex) a beamer presentation where I want to make a clickable web link, twice. It works in one case, not in the other:
This case works as expected:
\href{http://forskning.no/skog-matematikk-barn-og-ungdom-pedagogiske-fag-skole-og-utdanning/2012/07/laer-matematikk-av-skogen}{\beamergotobutton{Lær
    i skogen}}

This one makes a button, but clicking it has no effect (and, yes, the link within is correct):
\href{villemo.com/blog/?p=2858}{\beamergotobutton{Utematte---Emma}}

Any ideas what is the problem?

A: You should try adding http://. That solved it on my computer...
