[Pharo-project] addToStartUpList and World extent

Hello Pharoers, I am using "Smalltalk addToStartUpList: self" to register DrGeo in the startup sequence, so a new drgeo window is instantiated fullscreen automatically if none exist. However I have noted, at least on iPad and Android, that the instantiated window is not set to the correct fullscreen extent (it is smaller). DrGeo Window instantiated later from user request are correctly set fullscreen. Could it be that World, at the startUp sequence time, does not know yet the screen extent? Should I use another kind of startup sequence Thanks Hilaire -- Dr. Geo -- http://www.drgeo.eu
