I have a parent frame and a child dialog. Dialog is Application Modal. Through the same application, I have added a tray icon to the system tray and I have added a popup menu to the tray icon. When I make the modal dialog visible, this modal dialog blocks the system tray also and hence double clicking on the tray icon does not trigger any action event. Right clicking the tray icon does not show the popup menu. Once the dialog is disposed, I am able to interact with tray icon properly.

This is reproducible only on XToolkit and not reproducible on Win32. I reproduced it on SolarisSparc10-JDS with Mustang-b48. Modal dialogs are not expected to block the tray icon. The spec does not say anything about this functionality.

I have attached a sample test. Execute the sample test. You would see a frame and a dialog. A tray icon is added to the system tray. Try double clicking / right clicking the tray icon. Nothing will happen. Close the dialog and try the same thing. You would see the popup menu / action event.
