Thx for reply. first I uninstall messenger with the uninstall on add/remove programs. I dont know how to remove it completly. Second, this is the only program that have this such of problem. Every of my soft works well. On 2003, before I install messenger 6 (messenger 5 was install before) messenger works well. Am I alone with this kind of problem ? Even if i reinstall messenger 5, I have the problem too. Strange, it can’t comes from a dll, or something ?
