Trying to use the newest 3.10.4 VM on my Xubuntu box (Version 9.04) with Compiz disabled I get a segmentation fault at this way: I start the image (a 3.10.2 7179 basic image) and try to put the fonts on demo mode (A thing I do usually to see fonts bigger) and get the crash, as follow: garduino@chavo:~/SqueakDev/3.10.2Seaside$ squeak Squeak3.10.2-7179-basic.image Segmentation fault 2016366172 UUID>initialize 2016366056 Behavior>new: 2016365964 >new 2016365872 >setTimeStamp 2016365688 >updateInstances 2016363564 >setMenuFontTo: 2015449304 [] in >setDefaultFonts: 2015449168 SequenceableCollection>do: 2015448500 >setDefaultFonts: 2015448316 >setDemoFonts 2015448224 [] in MenuItemMorph>invokeWithEvent: 2015448132 BlockContext>ensure: 2015448040 Cursor>showWhile: 2015447864 MenuItemMorph>invokeWithEvent: 2015447772 MenuItemMorph>mouseUp: 2015447680 MenuItemMorph>handleMouseUp: 2015447548 MouseButtonEvent>sentTo: 2015447456 Morph>handleEvent: 2015447364 MorphicEventDispatcher>dispatchDefault:with: 2015447272 MorphicEventDispatcher>dispatchEvent:with: 2015447180 Morph>processEvent:using: 2015447088 MorphicEventDispatcher>dispatchDefault:with: 2015446980 MorphicEventDispatcher>dispatchEvent:with: 2015446848 Morph>processEvent:using: 2015446756 Morph>processEvent: 2015446664 MenuMorph>handleFocusEvent: 2015446388 [] in HandMorph>sendFocusEvent:to:clear: 2015446480 [] in PasteUpMorph>becomeActiveDuring: 2015446296 BlockContext>on:do: 2015446204 PasteUpMorph>becomeActiveDuring: 2015446020 HandMorph>sendFocusEvent:to:clear: 2015445928 HandMorph>sendEvent:focus:clear: 2015445836 HandMorph>sendMouseEvent: 2015445692 HandMorph>handleEvent: 2015445392 HandMorph>processEvents 2015445484 [] in WorldState>doOneCycleNowFor: 2015445300 SequenceableCollection>do: 2015445208 WorldState>handsDo: 2015445116 WorldState>doOneCycleNowFor: 2015444932 WorldState>doOneCycleFor: 2015444840 PasteUpMorph>doOneCycle 2012787260 [] in >spawnNewProcess 2012787444 [] in BlockContext>newProcess Cancelado With Compiz enabled I get the same behaviour.

Hi Gary, You should check with the people at Squeakland, http://www.squeakland.org/ possibly through their mailing list at http://lists.squeakland.org/mailman/listinfo/squeakland They are much more oriented to educational use of Squeak, although there is a lot of cross-pollination on the developer list too.
