Well here goes nothing: I'm running Windows Vista Ultimate with an Nvidia 9800 GX2 graphics card. I recently downloaded Second Life and I've been enjoying it so far until I ran into this issue.
I bought several walks and skins for my avatar, however when I attempted to use the walks (by equipping them and then placing the menu controls on my HUD), I found that I had no control over anything. I tried clicking on the "start" button, but it didn't respond. Any extras that came on the HUD didn't work either.
So, how do I clear this problem up? I've been all over the internet and these forums, yet I can't find any solutions.
