Hi All, I've got a Text object which I can inspect the string or the runs, but when I attempt to inspect the text object itself Pharo goes into a CPU loop and becomes unresponsive. I can't interrupt the display (Ctrl-.). I've attempted to step through the code to find the problem, however Pharo is going into a CPU loop when returning from GLMMorphicPageRenderer>>render:. I've included the stack trace leading to #render below. At the moment I'm struggling for ideas on how to track this down. Any suggestions? Thanks! Alistair The stack trace just before returning from #render: is: GLMMorphicPagerRenderer>>render: GLMMorphicPagerRenderer class(GLMMorphicWidgetRenderer class)>>render:from: GLMMorphicRenderer>>renderPager: GLMPager>>renderGlamorouslyOn: GLMMorphicRenderer(GLMRenderer)>>render: GLMMorphicTabbedRenderer(GLMMorphicWidgetRenderer)>>renderObject: GLMMorphicTabbedRenderer(GLMMorphicWidgetRenderer)>>renderWithTitleOrNil: GLMMorphicTabbedRenderer>>render: GLMMorphicTabbedRenderer class(GLMMorphicWidgetRenderer class)>>render:from: GLMMorphicRenderer>>renderTabbedCompositePresentation: GLMTabbedArrangement>>renderGlamorouslyOn: GTInspector(GLMCompositePresentation)>>renderGlamorouslyOn: GLMMorphicRenderer(GLMRenderer)>>render: GLMMorphicWindowRenderer(GLMMorphicWidgetRenderer)>>renderObject: GLMMorphicWindowRenderer>>render: GLMMorphicWindowRenderer class(GLMMorphicWidgetRenderer class)>>render:from: GLMMorphicRenderer>>open: GTInspector(GLMCompositePresentation)>>openWith: GTInspector(GLMCompositePresentation)>>openOn:with: GTInspector(GLMCompositePresentation)>>openOn: GTInspector>>openOn: GTInspector class>>openOn: GTInspector class>>inspect: Text(Object)>>inspect ^^^^ This is where I'm attempting to inspect the object.
