Upon installing Squeak 5.1 (both 32-bit and 64-bit) on Windows 7.1, customizing the user interface, and attempting to save the project, I received a popup window entitled with the following error message:
Error: subscript is out of bounds: 53
Closing the window with this title resulted in a list of the following error messages on the left side of the main Squeak window:
----- error messages follow immediately after this line ----- ***System error handling failed*** MessageNotUnderstood: UndefinedObject>>form Project class>>tryEmergencyEvaluatorForRecovery: Project class>>handlePrimitiveError: MorphicProject(Object)>>primitiveError: MorphicProject(Project)>>handleFatalDrawingError: [] in WorldState>>displayWorldSafely: BlockClosure>>cull: [] in MethodContext(ContextPart)>>handleSignal: MessageNotUnderstood(Exception)>>signal UndefinedObject(Object)>>doesNotUnderstand: #form [] in WorldState>>drawWorld:submorphs:invalidAreasOn: Array(SequenceableCollection)>>do: WorldState>>drawWorld:submorphs:invalidAreasOn: WorldState>>drawWorld:submorphs: PasteUpMorph>>displayWorld [] in WorldState>>displayWorldSafely: BlockClosure>>on:do: WorldState>>displayWorldSafely: WorldState>>doOneCycleNowFor: ----------------- Type CR to enter an emergency evaluator.
Type any other character to restart. ----- error messages end immediately before this line -----
Attempting to close Squeak by clicking on the close button of the Squeak main window did nothing; I was forced to use Task Manager to quit the process.
A similar error message also occurred when I attempted to save the project in Squeak 4.6; however, I was able to save the project normally in Squeak 3.9.
How can I tweak Squeak 5.1 to save the project normally?
