I read earlier threads about version 1.4 doing this and how subsequent revisions were supposed to correct the problem but here it is all over again. It occurs on one of my older conputers with Win98SE installed. I had just upgraded to 4.2 and started to load it for the first time when the program froze while enabling FireFox. Every subsequent attempt had the same results. I reinstalled the program and got the same results. Any ideas?
