Thank you I fixed it already and including the show windows area are now
black and author comments text are now white color in black background.

Help!
I would preferred to uses both key and mouse to advance slides manually.
BUT why some of my HTML presentation cannot use both? ONLY left mouse
click to advance slides and some of the slides must use Right Click and
select Next slides?

No problem in PPT file or presentation except and ONLY in HTML web uses.
My PP is 2002/xp and I must used Manual mode for advancing slides
because different length of narration and texts.

Any advice would be greatly appreciated.
