Comment 36 for bug 872207

Hi guys;
     I had one other thought. Yes I am using ubuntu 10.10. But I am also using Linux Mint 12 Gnome RC and Lubuntu 11.10 Desktop amd64 on virtualbox, trying them out to see if I might prefer them for my next OS. My emails that come in to my ubuntu 10.10 are also present, when I check my email in Thunderbird on lubuntu and mint (I installed Tbird on lubuntu.) In neither of those systems do I have the disappearing menus in Thunderbird - at all. Somehow those systems seem immune. Doesn't seem likely to me, since they are both ubuntu-based. However this does seem to be the situation and I've been using both of them for about 2 weeks now.
