Some notes:

• If a project on a cloud is opened by another instance, then show Attention dialog, and not open this project again.

• If a project on a cloud is locked or checked out, then an Attention dialog shows for user to decide whether they would like to open it as read-only or not.

  • Choose yes to open as read-only.

  • Choose no to attempt an unlocked / checking in of this project.

    • If when unlocked/checked in successfully, then open it normally;

    • otherwise, a message displays “This file can not be unlocked/checked in. It is opened as read-only.”, and opens as read-only.
