MAIL
For example, when a user opens a message, the Read Message window opens. The Read Message form is also cached, without the message text. The form is then used to display any additional messages that the user opens in the same window. This eliminates the time it takes to close the first window and open a subsequent message in a new one.
You can enable this feature globally, which enforces it for all users. If you do not enable it globally, end users can still enable it on an individual basis by setting a Domino Web Access preference.
To enable reuse child windows globally, edit the mail server's Configuration Settings document and check "Reuse Child Windows" under Other Settings.
To disable reuse child windows globally so that the end user preference "Reuse child windows" does not appear in the client preferences, use the NOTES.INI setting iNotes_WA_DisableReuseChildWindows=1.
