I'm a medical transcriptionist who recently upgraded to 4.0. After hours of troubleshooting, have concluded it's causing a problem I never had before with my Olympus AS-4000 transcription pedal. Now when I open voice files to transcribe them within FTP, the pedal no longer automatically backspaces a few seconds when I lift my foot. I must manually depress the pedal to get it to backspace -- time-consuming and frustrating. This all worked perfectly together in 3.0. Can I change back to 3.0? Thanks.
