I am currently using Directory Opus v11.10 x64 running on Windows 7 x64 Ultimate with all Windows updates up-to-date. I have noticed a few times over the last couple of weeks that doing something as simple as renaming a file on the desktop (local C: drive) doesn't take effect immediately and I must hit F5 or refresh in order to see the change. In a couple of instances when deleting a file. I press enter and the file does not show it has been deleted but if I try to delete it again I get a file not found error. In this case I had to close Directory Opus and relaunch before it showed as gone. Again, this is happening on my local C: drive which is an OCZ Vertex 512MB SSD. It has also happened on my local D: drive which is a 1TB 7200RPM Western Digital drive. Also it is happening when I make file changes or deletions on my QNAP 4-bay NAS device which is attached via local IP address.
I hope this can be looked at asap.
