The coversations registry localized at my docs-> my registries (sorry i dont know if it is the correct name i dont have in in english) should automatically open with the Log Viewer instead of internet explorer 8 , i try to force it also but it open again with IE . On the log viewer that i have to open in manually is on MP!Live Folder should have a combobox or similar to open chats conversions  of multiple MSN users because i have marked the box to have a separate folder for each account of messenger so the log viwer should be able to select wich account i want to see the logs...
