Photoshop Window remains in front

When using FF3 in Photoshop CS6, the Photoshop window won't go to the back, behind the FF window.

It works as normal in Photoshop CS3 and CS5.1

I have to either:

1) manually move the PS window off to the side so it won't obstruct my view of FF before I start FF, or
2) Use FF in one of the other PS versions

I'm running Mac OS 10.7.4 on the latest MBP (non-retina), 2.3 GHz, 8 gb RAM

OK, screenshot attached.

You can see the Photoshop window in front, however you'll see that the current document running via the menu is Filter Forge.

The Filter Forge window is in back of the Photoshop window.

Also, when I was taking the screenshot, I went to the Finder and the Photoshop window stayed in front in the Finder too.

After I hit "Apply", the photoshop and filter forge windows both disappear and all I can see is my finder. If I click on the photoshop or filter forge icons in the dock, then I'll get a progress bar pop up, but no windows. It is hard to capture it with a screenshot because the screenshot isn't very informative. I don't know if I can record this via quicktime; if I can, I'll try making a youtube video of it.

I did do some troubleshooting and found out that if I have my photoshop document docked as a tab in that main photoshop window, this will not happen. However, I purposely have the "Open Documents as Tabs" unchecked in Preferences > Interface because I have a hard time reading the document names when they're grey tabs.

Thank you. I've asked our testers to reproduce this.

Thats not how it should be on a MAC..???
i have that from the day i started to use FF on my MAC..

I now move the Image im working on down so its out of the way ..
FF window is ALWAYS behind the image im working on .. ALWAYS .

So i hope this gets fixed because its a pain in the butt... lol
