Dear Wolfgang, I sent an e-mail about problems with my simplefonts. I got no reply since my example had fonts that were probably not available to you. But the problem does not relate to the Gaelic fonts that I had been using. I am sending this file instead. The fonts below can be swapped about. The main font is always typeset as requested but the others are not. Am I doing something really silly? The readout from the console is below. I am using Context Minimals MarkIV on a Mac. Help would be appreciated. Thanks, Charlie \usemodule[simplefonts] % load the module \setmainfont[TeX Gyre Adventor] \starttext Hello World \blank[big] \simplefont[TeX Gyre Heros] \blank[big] \simplefont[Zapfino] Hello World \stoptext The argument "/Users/charlesdoherty/Documents/TestFolder/Untitled.tex" is not a valid TEXROOT path.
