Is anyone else doing the exercises in this series? Everything has worked fine for me in parts 1-3, but the latest installment isn't working... passthru.c for Stage 1 compiles with no errors, but when I try to execute the resulting passthru.exe, nothing happens. No dialog box appears.

I've double-checked my make4.bat, passthru.rc, and passthru.c files, and even had my wife check them as well. Everything is entered correctly.

Anyone else having a problem?
