Terminate button in the debugger

Am I correct in assuming when the terminate button in the debugger is red, then a process is running. If that is the case, how does one determine what that process might be?

Right now, as I write, I’m unaware of any process that could be running. Clicking the red button has no effect. There are times when this button is red and grey and no apparent logic to its state.

Would appreciate some clarification.

Thanks,

When a method is running - the name is in the title bar of the debugger window and the button is only RED when you have breakpoints enabled - so you can halt the currently running method.

It’s grey when there is no method running.
