I had the most horrendous experience yesterday while doing a gig with my 12" powerbook 1.2 GHz, 1.25 RAM. During rehearsals everything was working like a charm but when we started playing Logic stopped on me 5 times during a 1 hour set, due to slow disk or something, not that I actually took the time to read the message with the audience wondering what the f**k was going on. Figured out that it had to be the vibrations since the only thing different from the rehearsal situation was the volume. We played a bit louder than we did on soundcheck and it seems that was enough to give my powerbook the shakes. Scary! The vibrations were not violent at all, nobody were jumping around on stage and feeling the box the powerbook was standing on I just felt a faint murmur from the bass. No jolts. Is there a fix other than building a freefloat suitcase? What are you're experiences? Ginge
