Yeah, ePER is only compatible with Internet Explorer (it says this in the install notes on the DVD). Firefox makes the menus go all weird and you can't click on any of the pictures to zoom in, and aparently Opera just takes you back to the main screen.
Firefox is the worst...opera is a better alternative but not 100%. If you go to a section where you have multiple exploded screens at the bottom, it bombs out to the main screen.
I'm a linux and mac user, so its kind of sucky. I have to dig out the old p3 laptop thats uber slow!
Still its the designer fault and nothing we can do apart from make the best of it. Still very usefull tool
