Hi all. I have used Jaws Standard since version 6 and it has worked with all Windows software. And, having trouble with Vista and IE8, have decided to go back to XP. The XP version I have is professional. When I tried to download Jaws 10, which I had just paid £110 for an up grade, it said it was incompatible. Having phoned FS I was informed I would need to pay another £169 for an upgrade to professional. I asked what I was paying for, like what differences the professional version had, but they were a bit uncertain. They merely said it would work with XP Pro. Can anyone tell me why this is and what their reasons are? Why are we paying more for a professional version of Jaws, when it doesn?t offer any extras. Any comments/thoughts would be appreciated. Ron
