Wow you have opened up a can of worms. There are lots of drawing bugs when your DPI is not certain numbers.
See: http://bugzilla.mozilla.org/show_bug.cgi?id=97861 OS/2 has these problems by default because our DPI is different than other platforms. On OS/2, 120 is the correct value for for, but it is not in the listbox. We are working on a redsign that will make this DPI thing more usable. In particular, it will add a "System Setting" item which will be the one to use. See: http://bugzilla.mozilla.org/show_bug.cgi?id=109464 There are lots of issues with DPI. Here is an interesting conversation that will help: http://talkgraphics.infopop.net/1/OpenTopic?q=Y&a=tpc&s=98519178&f=44419488&m=7711992153&p=1 Basically, DPI is kind of a misnomer in Mozilla. What you are measuring is ppi which is not the same as dpi. I hope this helps somewhat. Mike Kaply IBM
