I have a bizarre font problem (actually the same I had a couple of months ago; I got rid of it by reinstalling everything including the OS, but I do not want to do that again). Both on the LyX running on Aqua and on X-Windows it replaces
\sigma by 1/4 (as a character) \theta by \mue (as a character) \alpha by (R) as a character etc. In Aqua its just the greek letters but in X-windows also \nabla and \int . Does anybody know how to fix that? -Jan
