For example, if I have mail running (or iPhoto, Quicken, etc.) and I click on the Firefox dock icon to open Firefox, Firefox always opens as the rear-most window, even though the task bar at the top of the screen shows Firefox menus. Further, I can select a bookmark from that menu, and even after the site loads, Firefox still remains the rear-most window. I have to manually click somewhere on a Firefox open site page, or the Firefox dock icon, to bring Firefox to the front. Just a minor inconvenience, but it's annoying nonetheless. This started with the OS X 10.6 upgrade, and continues with 10.6.1. Any ideas? Thanks in advance.
