File copying not possible

Often when I enter a directory with a lot of movies, I experience an error that I cannot move some of them - a dialog that someone uses the file pops up and, after few retries, moving operation succeeds.

After some examination, it turned out that the file is locked by DOpus itself, during examining movie for dimensions and other column parameters. Wouldn't be smart for DOpus to cease such file inspection if an action get invoken on it?
