Guys, something happened the other day that really has me puzzled. FirstDefense, for the very first time, was not able to save me from a major problem. Fortunately we got the problem fixed although I am not sure how. This happened on my wife's pc which also has FirstDefense installed, yes, we have two licenses for FD. This is what happened: Every time that FireFox has an upgrade of any kind, my wife needs to reboot her computer; we do not know why, I never need to but she does. We both have WinXP Home but she always gets a message that her system needs to be restarted, not FireFox needs to be restarted, BUT HER ENTIRE SYSTEM. So she has always lived with that minor nuisance. The other day she upgraded to FireFox 18.104.22.168 and sure enough received the message that she need to restart her entire system. So she shut down her system properly using the usual Microsoft recommend procedure. Upon restart, she received a message that her system had not been shut down properly. I was there when she did it: she did indeed shut it down properly. Anyway, after the usual screens including the FirstDefense pre-boot screen … NOTHING! Nothing but a blank, black screen … and it just stayed that way. I said to my wife, no problem, I'll just reboot your system and boot into another Snapshot and get rid of the FireFox upgrade. Restarted her pc, went into the FD pre-boot screen, switched to another Snapshot, continued the bootup … NOTHING! Same blank, black screen, FirstDefense was not saving us. I tried this several more times, same result. This was the first time ever that I have seen FD helpless. My wife has the most recent version of FD on her system. Not really sure what to do I just booted into the pre-boot setup BIOS screen and played with her boot up sequence, you know, what boots up in what order. I decided not to change anything, so I got out of the SetUp without making any changes. The next time I tried booting up her computer IT WORKED, we booted up into the original Primary Snapshot. I decided to keep her FireFox upgrade and everything has worked ever since. Does anyone have any idea why FirstDefense was unable to boot to another Snapshot, and if so, what should I do the next time, if ever, this happens again. Thanks.
