The strange thing is that the screens in Firefox do transfer data between them as they are intended to do, but the windows just don't close when the window close scripts are activated. They also issue the no properties error message.
I read the FAQs on this forum for explanation of the no properties error message. All I found were cases that showed code and someone suggested code changes and the result was the error message went away.
I did not find an explanation of what the no properties message means.
Can anyone explain what it is intending to tell me?
