Well, I am pretty sure that this has to do with CPU, the script was still a little too taxing on CPU so I made a couple changes. Clear your cache and restart your browser... I had to drop some of the features of the bar to clear the problem though ~~ all that work for nothing, lol.
It worked fine for me and some others... but that's because I have an athlon 3000+ ~ I think you told me your CPU was 1GHz ~ that might have been the issue.
