I don't remember the exact details, but I did try the G command, and it didn't work out. The problem was something like the program had nowhere to return to, so just ending with RTS would crash, and ending with a call to ExitToShell() would just restart At Ease and put you right back in the secure environment. I had to trick the computer into executing the program as a subroutine from inside another running program, which is accomplished by using the drag hook.
