Homegroup tree and searching

In windows 7 x64, when I open a remote computer in my homegroup, I see the usual icons like Music, Pictures, Videos. If I open Videos from here by doubling clicking it in the file list, I see all the videos and everything's fine.

However, if I open the folder tree and click on the Videos node in the tree under this computer, I get blank icons with no text and no context menu and I believe I'm getting one blank icon for each location in the library.

Is this a bug?

Second question: if there a way in Opus 9 to search a library location on a remote machine in my homegroup like I can from explorer's search box that shows in the upper right corner? I like this search feature in explorer because it's using a search index that returns very quickly and searches file attributes like Artist, Album, etc and that's necessary when searching hundreds of folders.

Thanks!

My first issue resolved itself after a restart.

My second issue remains: how to search a library using its index?
