Importing Powerpoints with JPEGs--Fuzzy

Hello,

I am able to import some PowerPoint presentations into Captivate that include some screenshots of an application we use. When in power point the screen shoots are very crisp, but when they get into captivate, they become fuzzy. I'm also noticing that some of the power point text itself is not as crisp as it is in PowerPoint--although it is not nearly as annoying as the screen shots. The problem gets worse if I increase the screen size of the captivate presentation from 640x480 to 800x600. Any ideas on how or if there is a solution to this? For this project, I'm hoping I will not have to recapture new screen shots directly into Captivate and can just leverage the existing Powerpoints--but we will see. I appreciate any advice.

Thanks,
Dave
