ex. Starting with both Illustrator and Bridge closed. 1. I open Bridge. 2. I double-click an Illustrator file, it opens fine. 3. I go back to Bridge and double-click another illustrator file, and Illustrator will not open it. This file should open as a new file (tab) within Illustrator.
This happens with "Edit in Original" from In Design also. It works the first time, (opens up Illustrator), but not a second time. I have to close Illustrator for this interoperability to work.
