Hi! For my university, lectures are posted online using Adobe Flash Player. The way they are done is there is sound associated with the lecture that plays, while a powerpoint slide is visible on the screen. On the side is a bar to navigate from one powerpoint to another. I am having an issue when viewing these presentation in that the powerpoint slide part of the video only shows the left 1/3 of the slide, tiled 3 times horizontally across the place where the entire slide should be. I can still use the navigation sidebar, and when the instructor's mouse moves over the left 2/3 of the slide I can see what should really be in those portions, but only for a short amount of time before it reverts to being tiled. Does anyone know how this kind of problem could occur? I know people using windows with firefox haven't had the problem, so I was thinking it was some problem with the settings of flash player in ubuntu.

A screenshot I took of the problem is here: http://img.photobucket.com/albums/v4...Screenshot.png
Thanks for the help!

Have you tried saving the PDF to /tmp and then opening it outside of firefox using a different PDF display program like xpdf, gpdf, kpdf, etc?

I didn't know this was a pdf? It doesn't appear like other pdfs do in firefox, and I haven't been able to discover any way of downloading it. It's basically a video in the main screen, except the video contains the current powerpoint slide and the instructor's mouse as it moves around. There is then a side portion that allows me to seek around to different parts of the video. The problems I am having are with the powerpoint slide part of things.
