My page shows only black! Help!

Actually, after deleting items from the top of the layering stack (bottom of Lectora's stack - it's upside down!) I have found that the problem seems to be the button that activates the swf:rollOver (mouseEnter) the button and an action makes the swf visible, rollOff (mouseExit) the swf and another action on the same button hides the swf.The swf is static, I use it as it has such a small file size and an excellent crisp edge when made transparent using parameters: wmode/transparent.Does anyone know why a button or two small actions may completely turn a page black?
