I have a long running server that uses appscript to send keystroke commands
to System Events.
It seems that System Events does not run constantly, or frequently dies.
Quite often, appscript seems to be in a state where it incorrectly thinks
System Events is running, and still sends commands to it, resulting in
failures.
Is there a workaround for this? A way to tell appscript that an app
definitly is not running, or clear some cache maybe that is lingering? I
notice if I start a different python instance, and send commands to System
Events, it correctly starts it up.
Here is a error dump from running essentially app('System Events').run()
when it thought it was already running -- the same happens with launch, or
any other command -- appscript can't get the terminology for System Events
because it isn't running:
