Thanks I did that but nothing changed, then I downloaded the so called newest version of iTunes and still no luck. As I was fiddling around a box came up with iTunes library being saved, which went on for some time. I felt anticipation growing and I thought, now it will work. I re-started computer and zip, still the same. I am perplexed as I have updated everything and I remember yesterday a funny iTunes icon appeared instead of the usual blue one on the tool bar and it said I had to upgrade my version to run this new iTunes, which I have done today to 10.6.8 and now I haven't seen hide nor hair of that again!! Arghh
If you are having basic computer problems such as an application that works one day and not the next, the last thing you want to do is start applying upgrades and updates. Often it will make things worse unless you are lucky and the upgrade happens to re-install the application component that went missing in the first place.
Did you run Disc Utility to verify your hard drive and repair permissions? That's the first thing I would have done. You need to repair permissions before installing any new software (be it the system update to 10.6.8, or an iTunes upgrade). Of course before doing any of that you should back up your computer, though in your case I wouldn't have backed up a computer showing issues because that might have replaced a good backup with one that had issues.
