I think there maybe an unlocking problem on my XP installation. I'll give some background info first...
I'm using three installs of LFS U22:
Main desktop - XP SP2 (custom built)
Main laptop - XP SP2 (hp TC4200)
Spare laptop - Vista32 RC1 (hp NC8000).
I've just experienced a third locking on the XP laptop (TC4200) for no apparent reason. I start LFS and it's in Locked mode. This unlocking hasn't occurred on my main PC, partly because I haven't been using it much, nor has it occurred more than once on the Vista installation. However, I am using two sound mods - PitSpotter and CSR Sound Remixer on the two XP installs, let me explain...
Just before the 3rd lock occuring on the TC laptop (and before I'd started LFS) I extracted a CSR soundset (XRR) to the \LFS\User Files folder. LFS was then locked when started. Now, I wouldn't have thought that this would have caused a lock, but I'm worried that using third party mods, especially sound ones could be interfering with U22, seen as there are sound changes in U22. I don't know, this could be a red herring, but I think I may remove these two mods for awhile and see if it happens again. It would be interesting to see if anyone else has been getting more than usual locks with this kind of configuration.
Also, as a result of this, I've drawn up a Change Log for recording ALL changes that I've applied to my LFS folder. Feel free to use yourself if you like.
