Hi Ben, Thanks a lot for testing and reporting such errors. Grafoscopio is now being migrated to the last Pharo / Moose stable versions and will be using Johan's Spec/GT-Tools bridge. I will try to improve the code in other regards. You can see the new interface (which is in GrafoscopioNotebook class) by executing 'OffshoreLeaksDB openIntroNotebook ' from your update Grafoscopio installation. To update it run: Gofer new smalltalkhubUser: 'Offray' project: 'Grafoscopio'; package: 'Grafoscopio'; load. self updateUI. I'll be finishing the Pharo MOOC before July 16 and after that I will be focused on Grafoscopio, but don't hesitate to report any issue you have. I will reply slowly meanwhile, but surely. Thanks again, Offray On 03/07/16 10:47, Ben Coman wrote:

Hi Offray,

After loading Grafiscopio from the Catalog in a fresh Pharo-50760 image, selecting Launch>New notebook... ==> MNU GrafoscopioGUI class>>open

Finder shows #open is only understood by GrafoscopioBrowser but GrafoscopioBrowser open ==> MNU: receiver of "/" is nil in #openDefault at... workingFile := draftsLocation / 'draft.ston'. where draftsLocation is nil, and searching all references show no method sets that variable.

In the comments is... GrafoscopioBrowser configureSettings but that ==> MNU.

Trying a rough guess to force... draftsLocation := '/home/ben/grafosocpio' asFileRefence lets the GrafoscopioBrowser open.
