I got a used laptop, Asus i7, Nvidia Geforce gt 550m, went from win7 to 10. All seemed good with SL. Nvidia updated, and added Nvidia Experience. Things seemed slow and different. Not better. Then I got a 10 update that took away my start button and any connetivity to the internet. I rolled back the update and things went back the way they were. Took the update again, and the same thing happened. I went back to factory settings, and SL is way too slow, teleportation fails often. I don't move when I try or stop when I want. All this with the latested Firestorm. Tried earlier versions of that and Singularity. Low graphic settings help but it isn't worth being on like this. Any ideas? Thanks Fritter

I want to use the name: ponzu shoyu. When I enter it I get the message that I can only use letters and numbers, what was wrong with this name? If I put shoyu I get the same result until I remove the u. It's not the number of letters, why is this word failing?
