But, basically, after updating METAFONT, using the 1-29 build, yap breaks. When I try to use yap after the update to look at a .dvi file, yap throws the following error, suggesting that modes.mf is missing. [Using 64-bit MikTeX 2.9.7250 under Windows 10 Pro.]
MiKTeX Problem Report
Message: METAFONT modes cannot be initialized because 'modes.mf' is missing.
Data:
Source: Libraries\MiKTeX\Core\Session\mfmodes.cpp
Line: 52
MiKTeX: 2.9.7250
OS: Windows 10 Pro, 64-bit, build 18363
If I do a re-install, update everything except METAFONT, problem solved. So, there is definitely something 'broken' with the latest METAFONT update (or, yap no longer plays nicely with METAFONT since the update -- one or the other).
