In Windows Explorer, when I am in a Subversion working copy folder, changing the contents of a file whose SVN status is 'normal' will immediately cause the icon to change from a green checkmark to a red exclamation point. In Directory Opus, the overlay icon will not change unless and until I hit F5, or navigate away from and then back to the folder.
Hmm...actually, with more testing...if I edit the file and then immediately switch to Directory Opus, the icon will change as expected. But if I wait 5 seconds before switching back to Directory Opus, the icon will not change. If I TortoiseSVN -> Revert... I am not able to get the icons to return to green without refreshing or navigating away and then back.
I don't know for sure but I suspect Opus caches icons for the files in the current directory, for speed, and does not re-load icons for files when they are modified. Maybe GPSoftware would consider changing that, or maybe I'm wrong about what's happening.
Do you see the second thing if you edit the file using Notepad? The different behaviour could be to do with how the editor modifies/replaces the old copy.
I think I may have figured this out, along with another issue I was having.
When I pressed "F5", Directory Opus was taking at least 30 seconds to refresh the folder (=any= folder, local or remote). I had a bunch of icons in "My Network Places" that pointed to shares that don't exist anymore. After deleting them, "F5" in Directory Opus is much more responsive (practically instantaneous).
On a hunch, I went back and repeated my TortoiseSVN test, and it now appears to be working as it should.
