I use Google Chrome on Public computers (windows XP) where I don't have admin rights. Google Chrome 16 works perfectly fine EXCEPT if I try to install any themes/extensions. Basically what happens is, I click to install a theme, it downloads a .crx file, and then does nothing. The .crx file stays on my computer and nothing is done. Other than that Chrome works totally fine as far as I use it so far.
Google Chrome 13 used to work perfectly fine, if I wanted to install a theme, it would download a .crx file, the .crx file would automatically be processed, the theme would be installed, the .crx file would be automatically deleted and all would work perfectly fine.
