Hi,
Not sure if yours is the same, however I changed the default (blue-ish) elonex theme for the one with a picture of a car on it (there were only these two options). After a fairly long-ish wait (can't remember what the dialogue box said) I got the new theme - there were still icons on it, and also tabs at the top in a similar fashion to the default theme. What I did notice is that the xgalaga game that I had installed from
littlelinuxlaptop.com had disappeared and I had to reinstall the game to get it back.
I changed the theme back to default by going to the settings tab and changing the theme, then everything was back to normal. How does this compare to what you've found?
Someone mentioned here that they'd found a re-set button on the back of the unit - maybe this would work (might lose your saved data though?)
Cheers
Jay
