Hello, I'm new to smalltalk, I've been trying squeak for some time, and recently I discovered pharo, so I downloaded the files and started to play with it. The problems: *) Halos behave inconsistently: I can only activate halos in the world menus. If I middle-click in the workspace, the preference browser or any other window, they don't appear. *) Preference Browser -> Keyboard: If I deactivate duplicateAllControlAndAltKeys and duplicateControlAndAltKeys, no matter the state of swapControlAltKeys, actions like copy are always invoked by the alt key. *) If I use the window menu -> window color and *drag* the pointer over the palette, the system slows down and the mouse is captured by the palette for several seconds (the more time you drag, the more time you need to regain control). Where I'm tenting: @ work: Intel Core2 Duo, 2GB RAM, Ubuntu 9.10 64 bits @ home: Intel, 512MB RAM, Ubuntu 9.10 32 bits What I'm testing: set #1: pharo-vm-0.15.1b-linux, pharo0.1-10373web09.07.2.zip set #2: pharo-vm-0.15.1b-linux, pharo0.1-10379dev09.07.3.zip set #3: exupery 0.15-linux, pharo0.1-10373web09.07.2.zip set #4: exupery 0.15-linux, pharo0.1-10379dev09.07.3.zip all sets with SqueakV39-sources.zip In all sets, both machines, the problems were the same. I've been playing with squeak 3.9 installed from the official ubuntu repository in both machines and it runs fine. I tried using that interpreter with the pharo images and it couldn't read the images due to version mismatch (6502 vs. 6504). I' tried to compile the last squeak but I didn't had all dependencies at hand, and it was too late. Thanks -- Ing. José Dinuncio Unidad de Redes Telemáticas Universidad de Carabobo
