To reproduce:
- Download a number of updates to a folder. Let's call it C:\Updates
- Downloaded updates should now be highlighted green in WUD
- Close WUD
- Rename the C:\Updates folder to "C:\WUD stuff"
- Open WUD. Previously downloaded updates should be white (unhighlighted)
- Change the download path to "C:\WUD stuff"
- Updates that were downloaded are still not highlighted
- Close and open WUD - updates are now highlighted
It's basically just that the highlighting isn't being updated after you change the download path.
