How can I troubleshoot and resolve issues with the Risk Navigator in TWS?

If you are experiencing problems with the Risk Navigator in TWS (Trader Workstation), there are several troubleshooting steps you can take:

1. Identify the Issue:
   • Determine which Risk Navigator is affected (Portfolio or What-if).
   • Note the exact behavior you are experiencing when trying to open the Risk Navigator.
2. Change TWS Version:
   • Changing the TWS version can often help resolve various issues by using different builds of the software. Here is how to do it:
     1. Always save your current layout before making changes:
        1. Go to File > Layout Settings > Save settings as...
        2. Choose a name and save the file to your desktop
     2. Close the TWS window
     3. Reopen TWS
     4. On the login window:
        1. Click on 'more options'
        2. In the versions drop-down menu, choose a different version (e.g., Stable, Latest, or Beta)
        3. Click 'Apply and restart'
     5. The login window will disappear briefly. When it reappears, log in and check if your issue is resolved.
   • Alternatively, you can change the version while TWS is open:
     1. Click on the 'File' option at the top left
     2. From the drop-down menu, scroll down to 'change version'
     3. Select the desired version (Stable, Latest, or Beta)

   2. Click on File > Global Configuration
   3. Choose the 'General' option
   4. Scroll down to "Memory Allocation (in MB)"
   5. Increase the figure from 768 to 2048
   6. Click 'Apply' and then 'Ok'
4. Recover or Reset Settings:
   1. Click on the 'File' option on the top left
   2. Choose 'Layout Settings'
