Is it possible to cancel an action invoked by the user?
Example: If the User chooses a specific action (crop in my case) I want to run a script that extends this action. In order to do that I have a script that runs when the user chooses crop. In that script I would like to first cancel the Event "Crop" and then offer some optional actions.

Adding the script is done by:

app.notifiersEnabled = true
var eventFile = new File(path + "myscriptextendscrop.jsx")
app.notifiers.add("Crop", eventFile)

But now I'm looking for a way to cancel cropping to do some action and then call crop by script later.

Thanks for any hint, best, Joerg
