@rwc, can you give a link to your site? (Please enable no-copy) Alternatively see whether the file wp-content/plugins/no-copy/no-copy.js is loading in your browser (or there in the source of the HTML output).
It would be interesting to find out what’s preventing no-copy from working on rwc’s site. 😀
@rwc, have you disabled javascript in your browser? Can you copy, right click, etc in http://felizsemdor.com/app/ ?
@rwc and @hogie can you please mention what’s your WordPress version? I tried with WordPress 2.7.1 with no issues.
@rwc, there is no issue with IE 7.
Looks like even the new release (2.8) doesn’t fix this issue.
