Hello,

I've loaded "Lilypond" into my computer (Windows 98).  When I click on the Icon on the desk top, I get a screen, the center of which is black.  A rapid series of files is shown and then a tool bar.  The only icons on the tool bar that are operable enlarge or decrease the size of the screen.  Nothing else works.  What should I do?

Many thanks for your answer.
