Anyone have problems viewing the Symbolic Trig Integration training aid?

A user has indicated this PDF shows black boxes for some of the screen prints (i.e., totally black) and that some of the functions show up as black boxes rather than as a readable function.

I can view them fine in WinXP and on my PB G4 Macintosh.





I have only viewed that particular page online. I downloaded it for more leisurely reading, but haven't gotten around to it. So, I can only speak for reading it online with Adobe Acrobat Reader 4.0 via my browser (Netscape 6). It looks fine.


As I scroll, many of the pictures or objects, such as the equations, etc., would become black rectangles for barest of a fraction of a second as I scroll through the file.

I wonder if it is a compatibility issue between versions of Acrobat. .pdf's sometimes are not so "portable".


Have you tried it directly with Acrobat Redaer 4.0?
I think it could be a Netscape plug-in progran (in v.6)


I run Mozilla Firebird 0.7 and have not experienced any problems. I have the acrobat 5 plugin.
