That's a very good point. I'll add a way of moving the window without the middle mouse button, sorry about that.

In the meantime, the config XML in the Visualistar directory has window position and size values you can modify.  At the top you should see the "Common" element looking something like this:

  <Common startMaximised="false" lastWidth="1080" lastHeight="1080" lastX="24" lastY="-9" alwaysOnTop="false" lastAudioDevice="1"/> 

You can close the program, change the lastX and lastY values, and when you restart the window position will be what you set.
