*just to clarify, do you mean that the first program has a command line or whatever to run the second? If so, the first program was designed to mask the second. It could have just set the ShowInTaskManager (I think thats the flag; Someone correct me) to 0 hiding it from the task manager, or it could load the second program into its own memory space... If it hasn't, it will show up in the WindowsNT or 2000 or XP Process viewer (95/98/me don't have a process viewer, only task).
