HAH! same here, I love it, but MAN!! can it get frustrating at times....
I also run SPB pocket plus...but I know it has something to do with s2u2. I removed it from the windows\startup folder (that's how u can disable it, it's called iLock2) and it's all good. Is this a known issue with s2u2 then? Or are we just some freaks?
Anyone know of another "locking" program I can try?
