When you are starting Publication Manager and Oxygen XML Author at the same time, if you try to open a publication or try to check out a topic from Publication Manager, you might see an error message The configuration file C:\Users\<username>\AppData\Local\SDL\InfoShare Client...could not be saved. The process cannot access the file because it is being used by another process. This is typically a timing message because your local client configuration is being accessed by both Publication Manager and Oxygen XML Author. Wait a minute and try the task again. If the message persists, submit an issue to the Infosolutions project.
