I don't know if this is a known issue, but when I try to have an underset and overset with subscripts, while the output looks fine, the display in LyX doesn't look right. In the example below, S_1 is overlaid on top of the greater/less than sign.
I'm using LyX 1.4.3-5 on WinXP. A\overset{S_{1}}{\underset{S_{2}}{\gtrless}}B Is this a bug ? Thanks, Alexander Sklar University of Miami
