Google Chrome window opening behind KMail window when hyperlink is clicked

On my husband's computer the Google Chrome window opens behind the KMail window when a hyperlink is clicked. My husband finds this very annoying. Is there anything I can do to make the Chrome window open in front of the KMail window when a hyperlink is clicked? Wheezy, TDE 3.5.13.2, KMail 1.9.10, Google-Chrome 41.0.2272.89 I have googled, but apparently there used to be a bug where Chrome insisted on staying on top, and that was almost all I could find. They seem to have over-compensated. I did find one that was what I wanted, I think, but it was for Ubuntu and in Ubuntu-speak and I couldn't follow it. DE specific? Thanks. Lisi
