Dokan sshfs doesn't stream, has gray Xes

Question

I installed Dokan sshfs so I can mount Linux computers as drives in Windows 7 64-bit. It seems to work, in the sense that I can view folders and copy files off of it. However, it doesn't seem like I can stream files, there are no thumbnails, and all the files have gray Xes:

Are these Xes placed by Dokan or by Windows? What do they mean?

Dokan SSHFS adds "offline file attribute" to those files in order to avoid unnecessary network access. You can control it on setting dialog when you mount a drive.
