Well I deleted the LW preferences but the activity monitor is still showing all the memory used up. So it looks like that is not the problem with LW4.10. Although there is only 5M or so free memory, most of the used memory is inactive and seems to be given up to other processes when necessary. The Virtual Memory allocation is over 3G and keeps increasing. I wonder what will happen if it runs out of disc space. Anyway thanks to LOTR I have a working version of LW again so I’m happy. I’ll try the later versions and post results, but 4.8.1 is definitely ok. Hopefully the LW developers will get on to it and provide a fix for 4.10 but in the meantime if you have the same problem I think going back to an earlier version is the only solution.
