My main forms testing page has bg #00ffff from when I was first experimenting with widget colors. Some time ago, fltk changed so that selected checkboxes and radio buttons use selection_color(). I had this set to the inverse of the background. Red. Not a good combination to say the least. Well, I finally got around to trying to fix it up a little. By the way, I was looking at that big page of inputs with differently-colored backgrounds that I made in February... At the time, I wrote that you guys had gotten the page down to 0:06 to load with clear_double_buffer(), immediate to load without it, and 0:09 to destroy the page. The good news is that it now takes the same amount of time with or without clear_double_buffer(), but the bad news is that it takes 0:12 to load and 0:48 to close.
