So far no love. OS10.4.I did the SPOTLIGHT=-NO- thing, followed by 'mdutil -i off' and then restart. After about 20min, PT got hung up, forced to hard shutdown. I'm willing to bet either I did something wrong, or that this is not the problem. I do have a 5lb lump hammer though..... ;)
It's not likely the problem. No other process can hang another unless they are linked via a library or IPC. Simply taking CPU time won't cause a crash.
There are a couple of other people on 10.4 who have freezes. Can you post the PT, OS, machine and video card info? Maybe some common element will appear.
