If I create a PROMPT in an install action and give the user the chance to cancel, ZCM doesn't care - it still installs.

I assigned Adobe Reader 9.3.3 update as a ZCM bundle to myself. I double clicked on the tray icon. It prompted me. I selected cancel. The rest of the install actions completed.

Seems the opposite of what one would expect a cancel to do.
