CompareIt3.8.exe crash1 crash2 (NOT the other way around)
CompareIt! will go to the first difference and possibly crash. If it doesn't crash, keep pressing PageDown but you will never be able to scroll past the difference. I admit, the difference is almost 32k characters but it happened for real files before I created this test sample.
Hope that hepls,

PS: congratulations on the 3.8 version but please update the CompareIt! version number from 3.75 in http://www.grigsoft.com/files.htm
