Folder does not show copied/pasted files in "My Documents"

Files copied and pasted, or copied/moved via DnD into the "My Documents" folder in another explorer window do not show up in this window until the window is refreshed via F5.

Observed on a German version where this folder is called "Eigene Dateien".

Copying the same file(s) to a subfolder of c:\ works well, the files immediately are shown in the target folder afterwards.

Maybe related:

• Create a folder within "My Documents" and it will not show up either, only after F5.
• Copy a file into that subfolder and it will only appear sometimes (but it has been copied). Once, after I had closed the window, then opened "My Documents\temp" again, the copied file was there. Another time not. Another time immediately. Huh?

I do not know if this has worked in some older versions or not (only checked back to 0.4.8).
