Launch Word/PPT/PDFs in New Window 2

I read the messages on "Launch Word/PPT/PDFs in New Window" but there was no response posted as to why the Web Address field does not hold the filename entered.- Create a text hyperlink that performs a "Go To"->"Web Address"- Enter name of PDF document in field- Check "Open in New Window"- Set window properties- Close Text Hyperlink Properties window- Reopen Text Hyperlink Properties window- PDF filename does not display in field- Change a window property and Lectora does not let you save changes because the PDF filename is missing (forcing you to retype filename)Any answers?
