Today WinXP and Argo have signed a peace treaty. Or, at least, a non-belligerance common understanding...:-) If you want to test the robustness of that treaty, please download again the program from : http://www.weaksignals.com and please send both negative and positive reports with WinXP and/or Win2k, so that I know how it behaves now. Thanks 73 Alberto I2PHD
