Here's one way to do it.
Create a directory in your LabVIEW x.x directory named 'wizard', and save the attached VI there. If LabVIEW is running, you'll need to restart it, but then in the 'File' menu, you'll have a new selection named "Supress Run on Open...". Select this and you'll get a browse dialog to select the VI to open. It opens it by reference so it will not run.
This is saved in LabVIEW 6.1, but works fine on 7.0 and 7.1.
You can also open it by opening a blank new VI, drop the the vi that you wanted to edit as a subvi and opening it from the block diagram of the blank one you just created. It won't run when opened.
