I can only use MMC only once, especially if I open any properties from any of the items (Except Web Proxy, Socks Proxy, or WinSock Proxy). After I use it the second time, the property window does not open, but when I try to close the MMC, it gives me an error saying that there are property windows open and that I have to close them up before I exit. This is very annoying. The only way I can restart the MMc is to reboot! (or logoff as a user) Task manager can't close it. Has anyone had this problem before? MMc is version 1.0
