I tested this today in the 5.1 latest version. Not the 5.2 beta.
If you are on a record editing and you are on a field with a picklist set up for On the Fly adding.
The popup displays and it works as it should.
BUT
If you leave your popup all filled in and then stop, leave the browser open, just go away for 10 minutes or so.
When you come back, click SAVE on the popup box, you get a new login page displayed in the popup because your connection has timed out.
This is highly confusing to users.
Is there a way that one could Close ANY popup windows showing after the when it times out. Im thinking that when the Login Page is loaded into a popup, somehow catch it there, close any and all popups and then reload the login page with the return to the original list.
Hope that makes sense.
Any suggestion on accomplishing this.
