that the windows did not act on repaint request (WM_PAINT, EXPOSE,...) Detailed explanation: - I implemented requestRedraw using the push approach (not using GraphicsWindow::_requestRedraw flag that I was considering) as there may be multiple viewers reading the flag and fighting to reset it after the paint request, while some viewers may not spot the request to redraw - I made windows call GraphicsWindow::requestRedraw when they receive appropriate message (WM_PAINT, EXPOSE, RESIZE,...) - There were issues on Linux that windows did not want to close using x button. Resolved by moving the test for DeleteWindow event from swapBuffersImplementation() to GraphicsWindowX11::checkEvents(). The difficulty was that DeleteWindow event is not coming using _eventDisplay, but through _display. - The last difficulty was that it is necessary to call ViewerBase::checkWindowStatus() to set _done to true when all windows are closed. This did not happened recently in ON_DEMAND run scheme. I put the call to checkWindowStatus() to eventTraversal. "
