What are “Queue 0” and “Queue 1” and what does the message “Queue 0 full” mean?

These queues store events that occur in an application. They are processed according to the FIFO (first in, first out) pattern.

In principle there are two event queues.

Queue 0: Rule processing
Queue 1: changedevents and external events

This message indicates that rule processing is taking too long. In this case, you should resolve the rule processing differently.

How can I detect Windows shutdown while my application is still running?

When Windows is shut down, the windows receive the closeEvent, that you can react to.

Another possibility is to catch window system messages (WM_QUERYENDSESSION/WM_ENDSESSION) via a DM_InputHandler and then perform the desired actions.
