I make powerpoint documents at work. Sometimes when changing pages
(during review, or during demonstration) there are black streaks that
momentairly flash in the display box. The (vertical) width and
location (in the display window) seem to change at random.

My question is, what causes this problem. I'm not asking for a fix, as
I imagine that's beyond our control. But curious if this problem is
confined to our systems, or a typical problem (although minor)
experienced by all.

Can you clarify what you mean by display box?  Are the black streaks
the full length of the screen?

I am pretty sure I know what is going on here but would like you to
confirm these points before I give you the answer and fix.

Powerpoint as I know it (I'm rather new) has a vertical column on the
left (about a fifth of the total display) which shows the pages to be
viewed (as icons). Clicking these icons will change the current
picture in the display box.

The larger display box to the right shows the current picture. This is
what I called the 'display box' in the origional question.

The black streaks are the full length of the display box, not the full
screen width.

Thanks, Patrice

I'm running a 2.6 MHz  P4, 512MB Ram.
I'm transitioning between screens by clicking the icons in the left
column of the Power point display.

Thanks for the help.

Could you give me some more information. What speed is your processor?
How much RAM do you have? How are you transitioning between screens?

Dave

are you saving it as a powerpoint presention file (it shows only the
slide show)before you show it? as it might play up if it is not
