During debugging the Athens-Crash I found something strange about TRCanvas (not responsible for the crash) 1. TRCanvas canvas instance variable is not a AthensCairoCanvas at all but an AthensCairoSurface 2. the canvas resp. surface is initialized with TRCanvas initial extent but a change on TRCanvas extent does not change the surfaces extent 3. Is this canvas resp. surface actually used ? Do we only need it to manage some external resources (path/ image forms) ? Can it be removed or at least renamed to something different. regards nicolai
