Modifying White text within a text box How to negatate?

[Guest]

When updating white text in a text box some slides automatically show the
negative view some howver remain with a white background that hides the text
.. How do I assign the negative attribute to all slides?.

You probably have a photo on your slide background. You need to change the
actual background color on your slide color scheme to something that will
contrast with your text. See http://www.echosvoice.com/colorschemes.htm to
better understand color schemes.
