Hi, I was trying to do a complete reinstall of Thunderbird and was trying to locate and delete folders which do not get removed after uninstall of Thunderbird. Anyway, I clicked something in C: Users... and everything on the desktop disappeared. So, I did a system restore to earlier in the day. Everything reappeared except some word and excel docs (Open Office versions). I searched for these docs in the Windows explorer but found nothing. So, I reopened the progs and was able to access the documents via recent documents. So I resaved them - but it said the files were already on the desktop (not that I could see) - anyway, I just renamed them and they are now there. Anyway, any ideas why this might have occurred as I'd like to avoid this problem in the future.
