See the screenshot
I started the RCP 32bit windows of Fuse IDE by double clicking the .exe file from the windows explorer.
This starts a window with a DOS prompt that prints the system out logs.
And then another windows with the real Fuse IDE.
I think the RCP of Eclipse has this fixed so there is no extra window in the background with the system out logging.
We should look into how we can improved this so Fuse IDE on windows looks better when getting started using it.
