DHello, I have a question regarding the Workspace when you execute code from there. Let me show with an example: I want to execute code instantiating an empty DrGeo sketch (a morph) then create programmatically content: |canvas| canvas := DrGeoCanvas new. canvas segment: 5@4 to: 10@20. canvas vector: 0@0 to: 2@2. ... The line with DrGeoCanavas creates and opens a new morph of a DrGeo sketch. My problem is: the morph only shows up on screen when the whole Workspace code is executed. I would like the canvas morph to show up when instantiated then get the construction code done step by step in the screen. Is the workspace code executed with higher priority than the user interface thread? Thanks Hilaire -- Dr. Geo -- http://www.drgeo.eu
