i downloaded and updated my java, security and gods only know what else. LW would still crash on start up!
gave up and used another P2P for a while, but once biten by LW always use it. so i tryed again this week.

i read that if your java does NOT show "Segmentation fault" after you run a check thru the Terminal ( http://docs.info.apple.com/article.html?artnum=301380 ).

then what you need to do is find and drag to the trash this file
com.apple.quicktime.plugin.preferences.plist

after i did that and re-started my mac. LW runs fine.

thanx for the help i got from here :0)
