Check your Firewall Permissions for Opera.

Or Install Opera Portable
Opera now has a portable option built into the installer, everything is contained inside the install folder no entries are written to the registry so just delete the folder to uninstal plus it makes it very easy to backup or take with you on a USB stick.
Get it at http://my.opera.com/desktopteam/blog...pshot#comments only 6.8MB
When you run the installer click on Options.
Change the Install path to another folder & change All users to External drive.
Should only take you of minutes.
Check if you still have the problem with Opera 11 snapshot.
Then either delete the folder or use Opera Link to synchronise.
