It just hangs with an hourglass. Other LC programs open, but not the one that I've spent a week working on. I'm guessing some repeat loop is automatically starting on program launch which is causing the hang, but I don't have any idea. Is there any way to alter the code some way to gain access to the program again?

Problem address with this code:

on mouseUp
answer file "open" -- select your stack
if it = empty then exit mouseup
set the lockmessages to true
open stack it
set the lockmessages to false
end mouseUp

You can't open a stack with LockMessages true:

If the lockMessages property is set to true, the following are not sent:

• Navigation messages (such as openCard, closeStack, and so on)
• ...

Try these options


1. Turn the messages off on the tool bar using the envelope icon to the left of the errors icon
before you open your stack. Then open your stack and fix the loop and then turn back on messages.

2. Try shortcuts to exit a running script.
Windows Ctrl + .
Mac Command + .

3. If the infinite loop was the problem then its always good practice to add "with messages" within the loop which allows the exit messages to be easier trapped.

Hope this helps.

You can open stacks, there are just no messages sent. In this case that's exactly what we'd want because the messages are running handlers that cause a hang.

It's convenient enough that LC puts the feature in the toolbar. I frequently open stacks that way while debugging a client's work.
