Just downloaded and installed it (after reading this thread) Had a system feeze up when i disconnected from the internet, but that could well have been me/finger trouble.
It seems to be a bit more colourful than the last interface. I believe it's been around a while now though so hopefully most of the glitches are ironed out. One thing i did notice that i like is, when you go to , control panel> internet options ,it gives you the choice/button to delete cookies and temp.files. with the last version i found that if i wanted to bin any cookies out of the Temp.I-net Files folder i had to do it manually via my computer> c:drive> windows.....
Not had any problems with it this 'sitting' so I'd say give it a try.
