So now the code reads:
*on* takePhoto
*if* the environment is "mobile" *then*
mobilePickPhoto "camera",300,300
*answer* the result
*if* the result is "cancel" *then*
*exit* takePhoto
*end* *if*
*else*
*answer* file "pick an image:"
*import* paint from file it
*end* *if*
*...*
Install the app, go to snap a photo, and before the dialog even displays,
the app dies. Tried again, same thing. Interestingly, I had
Focus at Willplaying music at the time, and *that* died at the same
moment. Anyway, same
drill: started the app a third time, switched to the front camera, took a
selfie, and no problems. Switched back to the back camera, no problems.
I quit the app -- double-tap home button and swipe it up, then open it
again. Took a back photo, app died, and took out Focus at Will's audio again.
Opened the app again, and tried the back camera again, no front camera.
Second time it worked.
Now I can't even replicate that: I quit the app, start it again, take a
back photo, no problems.
In all cases where the app gets to the answer statement, the answer dialog
is empty.
