If you need to do transcription using vScription and Winscribe at the same time, you can have both applications running at the same time and switch between them as needed and your foot control will work with both at the same time.
In order to do this, you MUST launch the vScription Controller first, then Winscribe Client. After that, you can load a job in either player at any time and control with foot control. If you happen to close the vScription Controller with Winscribe Client still open, you will need to close the Winscribe Client and then restart the Controller then launch Winscribe Client again to get functionality back for both applications.
This has been tested with Winscribe Client 5 and Controller version 1.82.
