Ok, so I've upgraded to Tiger. And I opened Mail... everything seemed to be going fine until I read approximately the third message. Then Mail crashed - and gave me the opportunity to reopen - and instantly crashed. Then gave me the opportunity to retry using new settings. I said no - but then I went through the cycle twice more (open - crash - reopen - crash - do you want to retry with new settings - no). I opened my account in Webmail and looked through the x4u messages - tried to find any Bundles - but there were none. OK, let's try that retry with new settings thing... (open - crash - reopen - crash - do you want to retry with new settings? - Retry) and I entered all the server settings for all four accounts I had in mail. And things opened smoothly and I can read mail - but I keep getting these alerts "<Something> has created new settings - do you want to use them?" <Something> varies - I've seen "Sync Server", "null", and some others. Anyone else see messages about new settings? I just realized I haven't quit and restarted mail since creating the new settings - maybe that's why it keeps asking? Andy
