Browser jumps to image whenever opening or closing a stack

Aperture: 3.4.5 3200900000000000.1

Mac 10.7.5

I have this SUPER ANNOYING bug where whenever I open or close a stack, the browser jumps to a specific image and selects it.

For example, I have an image in my library called RC5_1040 - Version 2

I was working with another image RC5_1048 and I made a few versions which exist in a stack. When I select the 1048 stack and open it, the browser selects RC5_1040 - Version 2 and scolls to bring it into view.

I move back to the 1048 stack and close it... and again the browser selects RC5_1040 - Version 2 and scolls to bring it into view.

No matter what stack I am working with, upon opening or closing it, the Browser selects RC5_1040 - Version 2 and scrolls to it.

I have multiple libraries on this machine and I have noticed this same behavior in another library as well.

Here is a screen capture showing the issue

In the video I open and close a stack based on RC5_1048 and each time the browser jumps to RC5_1040 - Version 2.

How can I make Aperture STOP autoscrolling to RC5_1040 - Version 2?
