The HTML won't win any prizes, but the following URL - and several others on the same site - work on Nav4 and IE4/5, but crash the NGLayout viewer app [12/10/98 nightly build]: http://www.snerpa.is/net/biblia/opin.htm As far as I can guess, the problem is that </FONT size> doesn't close a <FONT size=n> tag. To test this, copy and paste this line about 100 times into a document: <FONT size=-3><SUP>1</SUP></FONT size>Xxxx. Debug:Dump Content, and watch things keep nesting deeper and deeper. Now try it about 200 times and the viewer crashes. (These figures for an 80Mb Win95 P120, probably different elsewhere). This is presumably an issue for <FONT color> and <FONT face> as well.

Fixed by correction to nsString::ToInteger().

verified fixed
