Modal popup while folder cruising

I frequently use the folder cruising feature while comparing folders (since Bridge doesnt have a folder comparison tool...)

Many of my folders are arranged per the following sample:

------------------

1600px

   A

      Discontinued

   B

      Discontinued

   C

      Discontinued

1000px

   A

      Discontinued

   B

      Discontinued

   C

      Discontinued

etc except many more than three subfolders.

---------------------

Where I would be comparing A to A, B to B, etc, with two windows open.

Unfortunately, if I have folder A loaded in each window and use folder cruising to open folder B in each, I get a modal popup once each folder loads which blocks the OTHER window from loading. This is even after changing focus to the other window. I have to manually click or press Escape to dismiss the popup.

Expected behavior would be no popup.
