Hi... I could use some help...

I've a tutorial document; 106 pages but shouldn't matter except to show
level of my frustration. This document has 100-150 "screen shot" graphics
and I want the text to flow around the text.

For each graphic, I've clicked FORMAT PICTURE / LAYOUT / ADVANCED / TEXT
WRAPPING style as SQUARE and all margins are set to 0.125. Then I move
(mouse or arrows) the graphic to where I want... however, as I move further
into the document, the graphics start to have a mind of their own.

1. This problem I can see immediately... when I move a picture towards the
top of a page... it "jumps" into the header. I can move the pic down to
line 4 or 5... and use the arrows to get NEAR the first line but not TO the
first line. This doesn't happen in the first 20-30 pages... then once out
of every five attempts after. Annoying but liveable.

2. This problem is highly-aggravating... happens when adding/deleting
text/pics BEFORE an established pic... again, as I get deeper into the
document. When I make a "several line change" (adding usually but also
deleting) or insert a new graphic... the next few graphics start running
amuck... they end up in the margins... or in the footer... or overlaying one
another. Usually it's graphics on the current or next page... once in a
while even 2-3 pages down.

Can anyone shed any light on what I'm doing wrong??
Thanks in advance,
Steve
