This behavior has been introduced with v0.9.0 because xlwings now allows you to control the app independently from a workbook. But in order to establish a connection using the current HWND approach, the app needs at least one workbook open which is the reason this currently happens.
We might be able to fix this though in case you're opening an existing book. See also #444.
