Why does Digital Performer stop when I switch to Reason during a ReWire session?.

There are two reasons for this:
1. Digital Performer must be set to run in the background. This is done in Digital Performer's preferences.
2. You must set OMS to run MIDI in the background. This is done in the OMS setup application under Edit->OMS MIDI setup. Enable the 'Run MIDI in background' option.
