Maybe this will help:
I just found an answer for you! Apparently Bridge interacts with Windows in a different way. It is actually the Window settings that you have to change:
1) Insert your card into the reader and ignore Bridge.
2) Select menu Start => My Computer
3) Right+click the "Removable Disk" icon for your card and select Properties at the bottom of the menu.
4) Select the AutoPlay tab.
5) In the drop-down menu, select "Pictures"
6) Under "Actions", the "Select an Action to Perform" radio button is probably selected, and if you scroll the list of actions, you should see that "Download Images Using Bridge CS3" is highlighted.
7) Do ONE of these:
7.1) Select "Take No Action" at the bottom of the actions list - the same list that contains Bridge in 6) above.
