Anybody else using Revit 2013 ever seen this window. It is separate from the Main Revit window. It seems to have no function. You can't drag it. You can right click the title bar to access the Move command. The drop down only contain Sheet. It doesn't appear to have any function. The item changes with the View that is open. You can also Hide it by right clicking the Title bar. And you can simply click the Red "X" to close it. But it occasionally re-opens on it's own.
I think I figured out what that loose window is. When I had a project open and I had something selected like a view or object it would look like the image in the original post. I double clicked on the title bar and it docked into the object options bar. It's a Type Selection drop down.
In the past we have seen odd behavior when workstations have multiple monitors in place, or a large monitor set to a high resolution. These issues are magnified if Revit is being utilized in the secondary monitor, as Revit attempts to use the primary monitor by default. We have also seen these issues if the Project Browser or Properties Palette undocked from the main Revit window.
If you have not already, I would verify that the monitor DPI is set to 100%, Revit is on the main monitor, and the Properties Palette and Project Browser are docked.
