Many thanks to Craig and Jacqueline for their suggestions. I had never used the “errorMode,” but could not get it to work. The “suspend errors” button (or menu command) seems to do what I want, but with a bad bug (see below). The “suspend messages” button (or menu command) does work as Jacques suggested.
I created a test stack that has one button with this script: on mouseEnter put random(1000) get missingHandler() end mouseEnter A. With neither “suspend messages” nor “suspend errors” in effect, when the mouse enters the button, the message box gets a number and an error is triggered by line 2’s missing handler. B. If I “set the errormode to quiet”, the same thing happens (so this did not suppress the error on line 2). C. If I choose “Suspend messages”, no number is put and no error is triggered. As expected! D. If (with “Suspend messages” turned off) I choose “Suspend errors,” the number is put but no error is triggered. As expected! But: I can execute case D once, but the stack then becomes unresponsive. If the mouse reenters the button, no number is put; and other controls will not execute their scripts either. It is as if having suspended errors successfully once, all messages get suspended, and nothing works until I restart. So I think “Suspend messages” will do what I want, but I would like to understand why “Suspend errors” (which would be preferable for my purposes, since it allows innocent messages to proceed) doesn’t seem to operate correctly.
