If I want to search for an email in the SENT ITEMS folder, I can only view for a short time before it automatically flips back to the INBOX.  Frustrating as I'm usually looking for a particular email and if I try to read an email in the preview pane (even after selecting/highlighting the item), the view flips right before my eyes back to INBOX.  I have to click back on the SENT ITEMS folder.  Is there a setting that is 'on' that I can turn OFF?????
