The crash log isn't a lot of help sadly as there's not much information about the thread that crashed except that it's somewhere in quartz. If I could reproduce this then I shouldn't have too much trouble finding the problem but after about 30 attempts on 10.5 and 10.6 no crash. I will make a debug build later tonight and put it through some memory testing tools to see if that throws up anything. Paul. |
