This is specific to Windows OS. Sometimes (very often) I'll try to delete a file (or rename a file) and Windows will say that the file is open in Adobe Illustrator and will not allow me to delete the file. If I'm using Bridge and I try to delete a file, at first, simply nothing happens. After a few seconds, an error message pops up that something has gone wrong with Bridge. This message will pop up again after a few seconds. Bridge becomes unstable and crashes shortly thereafter.
