Do timer events interrupt App sleeping?

General

If one calls:

App.SleepCurrentThread(milliseconds As Integer)

then will timer events still trigger and perform their action code during the sleep duration?

It depends on whether you call it in a Thread or an Event (on the Main thread).

If you call it on the Main thread, then almost everything will be blocked (except for other threads, which will keep going).

If you call it inside a Thread that is not the main thread, then nothing will be blocked.

There may be some edge cases having to do with modal dialog boxes in macOS, but in general it works this way.
