The only viewer I have tried is Phoenix..latest version. I know Firestorm is in beta right now. I will definitely be looking into Firestorm soon. If the graphics can match the crispness I desire..and I can get the UI I want then I will switch permanently. I prefer the viewer 2 UI and how it doesn't clutter my screen up unless I want it that way. As I said I don't have these issues on Phoenix. My photos are working fine right now since cleaning local cache. I don't crash often but I still crash more than I would like. When I began using viewer 2 before the auto updates started I could stay on all day..dance..teleport...and MAYBE have one crash if any. Now I get 2 or 3 crashes per day..sometimes more. Certain sims...I rez in and start walking and bam...crash. I don't get that result on Phoenix. I REALLY LIKE viewer 2 but I am not happy with the performance at this time. I will keep reading the boards for answers if there is one
