Korn privacy violation

With Korn set up to display email from two different accounts in the system tray (my wife's and my own) using right click to view first my email and then my wife's will produce the following privacy violation:
I right click Korn and select View, which loads up and views the subjects of my emails, I then exit the preview
then
my wife does the same on her icon, she will see my subjects, etc while Korn shows a dialog box "Progress - rechecking box".
This is a clear privacy violation, my wife's preview should never, even for a brief second, show my subjects. And since it can take many seconds for Korn to fetch the new set of headers, my data remains viewable for quite a while.
