I decided to upgrade to Ubuntu 11.10 64 bit today and after the 5 hour install and 2 hours of farting around to make it usable, I think I'm back to where I started.
This seems to be a major upgrade of the OS (Linux 3.0.0-12) and Gtk3. They must have taken some of the fat out of Unity as it ran on my laptop this time and didn't tell me my stuff was inadequate.
I tried ScriptBasic with GTK-Server and my GUI example I scripted worked. (fingers crossed on that one)
A lot of work to be current.
