Solution

Workaround: Open another file that the current pod file is not being displayed in. The exception log in this indicates that another process is holding the file. Opening a different file appears to release the file.

To check which process is holding the file please ask the user to run
procmon utility, capture all events (without filters) and save them as
PML format.

Procmon can be download from Microsoft web site:
