How to Quit with a button

[William Prothero]

Richard:
Thanks for the input. I’ll stop messing with the doMenu approach. I’ve tried a number of things to get my app to shut down without crashing the app. I know it must be possible because the toolbar menu quits fine. I may just stop trying to use a script to quit. It’s not essential since the toolbar menu quits fine. Anyway, I’ve tried locking messages, closing all substacks, delaying the “quit” with a send command, and it crashes no matter. But, a bare stack works fine. I wonder if I’ve come against some other bug in V7.0.1 that the quit command triggers. Anyway, it’s too complex for me to worry about at this stage, so unless there are other bright ideas about what might be happening, I’m going to remove the quit button.
Best,
Bill
