Street Atlas 6 in Classic mode - font problem


I am running Street Atlas 6.0. When I run in under Mac OS 9.2.1, it works fine. When I run in in Mac OS X 10.1 in Classic mode, the fonts in the route table are about 1 or 2 pixels high. Just got this program, so have not run it under earlier versions of Mac OS 9 or X. Anyone seen this problem or have a suggstion?
