Hello All: We are having some problems running HCT 11.0 on WinXP SP1. A driver which passes HCT 10 is failing HCT 11.0. I am new to this and was wondering if there is any documentation which describes in detail what the HCT 11.0 tests are doing. Thanks for any help! Val --------------------------------- Do you Yahoo!?
