Hello again, I have the impression you can basically forget about the grid mode when using formulas. I started writing a simple text containing lots of math. When I turned on grid mode I basically saw ... well ... not at all what I expected. A simple example is: (watch the last line) -------------------- SNIPP -------------------- \setuplayout [grid=yes] \showgrid \starttext x \startformula x \stopformula x$\tilde I$ \stoptext -------------------- SNIPP -------------------- Note that in normal Text $\tilde I$ is correctly aligned. The combination with the big formula is a problem. But it is clearly not the only situation in which problems with grid and formulas occur. Leif Albers P.S. Is this list the correct place for bug reports?
