Since I installed Windows 10 Second Life has not worked. Everything I do happens in 4. If I talk in world or chat it broadcasts 4 times. If I try to purchase anything I purchase 4 of them. If I build anything it builds 4 of them. With breedables it creates one and makes one a non working copy OR just makes the original worthless and not working. I filed a ticket but but they have had me going the the newbie steps and I have been in game over 10 years. I tried those before I ever contacted them. When I told them that they just stopped replying. It has been 3 days since I heard from them and over a week since I can basically do nothing in game. Hope this helps.
