I've got this error when the debugger is triggered in a headless image. So, #MNU. I had a look at the NonInteractiveTranscript and it has this method missing indeed in 3.0. I've added a basic one but we could benefit from enhanced debugging abilities on that front. As I am running on a server without any graphics abilities, it would be welcome to have this fixed. I added this to the startup script to patch the thing: Author fullName: 'PhilippeBack'. "Avoid yet another question..." NonInteractiveUIManager compile: 'openDebuggerOn: process context: context label: title contents: contentsStringOrNil fullView: bool ^ self nonInteractiveWarning: ''Opening Debugger''' classified: #'ui-requests'. So far so good, but it turned to: An attempt to use interactive tools detected, while in non-interactive mode Opening Debugger NonInteractiveUIManager>>nonInteractiveWarning: NonInteractiveUIManager>>openDebuggerOn:context:label:contents:fullView: SpecDebugger class>>openOn:context:label:contents:fullView: Process>>debug:title:full: GRPharoPlatform>>openDebuggerOn: in Block: [ process debug: anError signalerContext title: an...etc... And the vm stopped again. Looks like: NonInteractiveUIManager>>nonInteractiveWarning: aWarnMessage ^ ErrorNonInteractive signal: aWarnMessage isn't too friendly. How would one get debugging info shown and just proceed or close the debugger? Closing the image is really hard to swallow here. Ideas? Phil
