Occasionally my code crashes when I test if sys.desktop.ActiveWindow.exists because "Cannot find the window with handle xxxxx".
The line immediately before the condition is sys.Refresh so I would have to be extremely unlucky for my object to be destroyed in the milliseconds since the refresh but it keeps happening.
Ho do I test this? Do I need to use isnull(sys.Desktop.ActiveWindow) instead?
