Hi, I created a convenience subclass of MooseTask called MooseCustomTask that allows you to easily display a progress bar. Here is an example: MooseCustomTask runWithProgress: [:task | (1 to: 500000) do: [:each | task increment ] ] description: 'Demo' length: 500000 Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow."
