Note that this is a feature (aka bug) of the LaTeX default font (Computer Modern), which uses the accent tilde in the text tilde position. If you switch to another font (for instance the similar-looking "Latin Modern Roman"), you'll get the correct tilde right away. Nothing we can do in LyX here, I'm afraid. Jürgen
