If the fixed version of Xolox that came out after 12-1-01 was working for you, and auto update is off, try changing the name of “hostslist.txt” to “Old hostslist.txt” before starting Xolox. Then when you start Xolox up try not to have any thing else running, or open any new windows.

This has worked for me in the past (it forces Xolox to make a new copy of the “hostslist.txt” for its self).
