This is because the first xymatrix is inside a hullNone math hull. This kind of math hull is intended for environments that would also work outside of math mode. Inside a hullNone you're neither in text nor in math mode (mode is undecided) and it is the responsibility of the environment properly interpreting math constructs. For example, the environment could interpret x^2 differently from a squared x (even if it is still represented as a squared x in lyx). There are some differences in the way a hullNone is represented in lyx with respect to a normal math hull. For example, a roman (not italicized) font is used. I don't know whether there's any advantage with respect to a normal math hull. The big difference is that a hullNone is translated to latex without any math container, such that math constructs would cause errors if the environment does not deal with them. I think that lyx issues that warning to make you aware of this strange environment, even if the screen representation would already be informative. If the warning bothers you, simply put the cursor inside the hullNone and issue the command "math-mutate simple" form the minibuffer. To return to a hullNone you simply do "math-mutate none". -- Enrico
