Jaunty hunging

[AFK]

Hi,
I'm using UbuntuStudio some time.
Ver.8 is working good but the newest 9.04 has a bug so
I can't use it.
After instalation, Jaunty looks like working but  sometime it hungs
and always hangs during updating.
I instaled Jaunty on 3 different computers (Pentium4, AMD64, notebook 
centrino)
and I found out the same signs.
So I returned to Hardy!
