Matthias Bläsing commented on NETBEANS-5070:
--------------------------------------------
As I see it, the problem is not the font metric, but the calculation of the
positions where differences in the calculations of the position at various
places in Sel.java and Term.java and maybe the fact, that calculations are done
in integer space, but that is a shot in the dark.
