I have been using computers since the Sinclair and currently I am having the most bizarre and serious problems I've ever had. There are indications that the source of these problems is a recent Firestorm beta. My current computers are an iMac and a Macbook Air running OS X 10.7 (Lion) and a PC running Windows 7. I also have an XP laptop on which I did not install Firestorm. I was entering Second Life on a regular basis using my Apple computers and, primarily, Phoenix Viewer and Cool VL Viewer. There were no problems. Then one day I started Phoenix and it said an update was available, so I installed Firestorm. Firestorm worked a couple of times and I liked the interface. Then the first problem started to occur - I lost the ability to right-click. Restarting Firestorm fixed that for a short while, but then it recurred. Eventually I decided to continue without right-click capability as long as I was able to do so. Shortly thereafter the second problem started - the pointer disappeared. Naturally, that made it almost impossible to continue. Yet the problems were just beginning. I was able to Cmd-Tab (OS X equivalent of Alt-Tab) out of Firestorm, but the pointer was still missing. I had to shut down the Mac using the power button. OS X came back up, but after several minutes (without restarting any viewer) the computer froze with the message: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." After the second restart the computer ran okay, but since people were waiting for me to return to Second Life and I was leery of using my iMac, I decided to use my Air. Since I didn't suspect Firestorm as being the cause of the problems, I installed it on the Air. Very shortly thereafter I had the very same problems. At the time I assumed it was some kind of issue with Lion, so I pulled my HP laptop out of the closet. I installed and ran Firestorm on Windows 7 and within one hour I experienced three Blue Screens of Death. By that time I did suspect Firestorm, so I went back to my iMac and started Cool VL Viewer, an older viewer that I had used many times. The same problems occurred in that viewer! I decided that the safest course was to download and run SL Viewer 2. However, the problems occurred again. My next attempt was to delete all OS X preference files related to SL viewers and try again to run SL Viewer 2. Even that did not work. Currently, I have not figured out a way to get on Second Life again using either of my Apple computers. On my Windows 7 PC I was able to do some OS upgrades and I can run SL Viewer 2. Please note that I have no hard evidence that Firestorm beta was the cause of these severe problems, but they did appear only after I had run Firestorm.
