"Device is already being used in project maker"

[Cyrix]

ZD projects can't be run when my PM and ZD are opened at the same time, with an error message "Device is already being used in project maker".

How can I release the device from PM?
Right now I have to close PM completely whenever ZD is running, but it is inconvenient for debugging between PM and ZD.

Thanks.
