Benjamin - Many thanks.
Your suggestion of World submorphs do: [:e | e delete ] was just what I needed to get rid of the taskbar. However, DisplayScreen hostWindowTitle does not work for me. I'm not using Spec but surely that should make no difference. Is it a platform bug (I'm on ubuntu 13.04) or are you using pharo 3.0? I'm on pharo 2.0 (there is no WorldModel as far as I can see). So, is DisplayScreen hostWindowTitle broken on pharo 2.0? ken -- View this message in context: http://forum.world.st/Deploying-a-polymorph-app-two-questions-tp4724525p4724550.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
