I've recently started using mkiv because of the fonts, but I have found lots of things that don't work. The trouble is, I don't know if it's just me, or whether I need to go back to mkii until things settle down. Can someone, PLEASE, tell me if they get any of the following problems with mkiv (I've included code snippets): Everything below works perfectly in mkii. 1) References to equations appear as '??' in the final document \placeformula[eq:pythag] \startformula a^2 = b^2 + c^2 \stopformula Pythagoras proposed \in{equation}[eq:pythag]. 2) References to footnotes appear as '??' inside \startlocalfootnotes...\stoplocalfootnotes \startlocalfootnotes This has a note.\footnote[fn]{Footnote.} See note \note[fn]. \stoplocalfootnotes 3) References to sections are repeated (e.g. reference to section 1 appears as '11' or ref to section 1.1 appears as '1.11.1') \section[sec:one]{Section one} It was in \in{section}[sec:one]. 4) \digits command falls over at periods or commas with "\textfont1 is undefined (character 58)." \digits{1.6} 5) \infull command does not work for abbreviations: falls over with "Missing } inserted." \abbreviation {KF} {Kalman filter} Rudolph Kalman invented the \infull{KF}.
