and another thing...!
Just found something else that the download must have done - sometime back (maybe when I updated SplashLite?) the volume icon disappeared from the notification area of the taskbar on my computer, and I had to use the more cumbersome volume control option instead but, since I deleted the SplashLite 1.7.1 download, the volume icon has reappeared. I don't know how a download in one folder can affect so many things!
I am using Windows XP.
