------- Additional Comments From svdw@udel.edu 2006-19-10 14:13 ------- I think I've isolated the problem. When Steam starts it also pops up a news window. Sometimes that news window fails to load properly, or just fails to load period. That is what's using the registry. To fix this you need to fix the steam start-up.
