Pathfinder only supports being open in one browser window/tab at a time. If you have multiple tabs/windows open with Pathfinder, then you may get an error.
If you would like to look at two different cases at the same time:
- Log in to Pathfinder and open the first case
- In your browser, open a new window in 'Incognito mode' or 'Private browsing mode':
- It will depend on your browser what this mode is called and how to open a new window.
- In Chrome, chose the settings, then 'New incognito window'.
- In the incognito window, log in to Pathfinder and open the second case
