Oddly enough, I have to click the search button in the start menu (or press win+F) *twice* in order to get the Search window to appear. Not sure what the significance of this is whatsoever.
Here's a screenshot of what happens when I do open it:
Note the weird search pane on the left, and the lack of a window title. The search pane is non-resizable and seems to contain absolutely nothing. Also, a lot of the toolbar menu options don't work, the Edit menu itself actually being completely empty.
Similar results are achieved when opening the Search pane in an actual directory; it brings up the weird Search pane, which is unusable. That is, of course, when it decides to do that instead of simply crashing explorer.exe first.
I also have NO idea what's up with the Cox Communications image in the upper right. In other Explorer windows, it's just the Windows logo. I do have Cox as my ISP but I don't know why that image is showing up in the search feature window when I've never seen it anywhere else for an extremely long time.
