Thank you very much. The "borderless window" idea is a great start. Step 1: Create main window as borderless Step 2: Figure out how to make it draggable without a title bar at the top Step 3: Figure out how to animate the "scrolling" of the text Step 4: Consider making the scrollwindow "transparent" some how so that the text can appear to float on the vdeo. I don't think it's possible but it would be nice though :) This is going to be a great little project and I am really looking forward to it - thanks again for the help. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
