Once you have installed JRE 1.4.2 by following the instruction in the FAQ forum, you may also want to upgrade your TRiLOGI software as the JRE 1.4.2 introduced some problem to older TRilOGI program and an updated TRiLOGI (now version 5.32) will fix those problem caused by the new JRE. To upgrade your program, just click on the "Help" menu on TRiLOGI and select "Upgrade" and follow from there.
