I am getting an Arduino Mega board for Xmas (I hope...!) and have downloaded the IDE in anticipation. This is on Vista, 64-bit. When I open an example sketch from the file menu the sketch opens in a new window (with the toolbar, etc.). So if open multiple sketches there will be many open windows (and will they all have found the correct serial port, etc?). Is this normal? Is it something I can fix in the preferences file? I'd like sketches to open in one instance of the IDE if possible. I'm thinking this must be a bug since it looks like the IDE supports tabs for sketches but I'll never get to use them, since each sketch is in its own window.
