mozilla thunderbird

I've been using this quite happily for a while, and am suddenly getting the undernoted message (and consequently no emails). "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and yo have enough disk space to copy the mailbox." Can anyone tell me what to do to fix this?

Do you know if your mailbox is stored in one particular folder on your hard drive? If so, one (remote) possibility is that you could right click on this folder, choose Properties and then Security. In there, allow all the users "full control" (or just "write" privelidges). All of these options appear on my PC which has XP Pro - yours may be different.

fraid I don't know where it is stored. I'll scroll through all thunderbird files and see if I can find out. But why would it change itself?
