I work on macbook pro intel with system mac os 10.6.6 Labelled equations, and only them, always stay in the editing mode (appearing blue on the screen and different from their appearance in the latex result). This does not affect the latex typesetting and the pdf files produced. This affects both rc1 and rc2 releases.
I am longing for the solution of this problem to switch to Lyx 2.0 and take advantage of its numerous improvements. Jean Kaplan
