 * Check seems to work for Firefox and Chrome (tested my blog using latest versions);
   IE – well it’s IE…
    However, in Opera 12.02 a line is shown:
 * Warning: preg_match_all() [function.preg-match-all]: Compilation failed: unrecognized
   character after (?< at offset 3 in ../wp-content/plugins/advanced-browser-check/
   output.php on line 87
 * Despite the settings, this may make ABC to show up mistakenly?

 * I have not been able to replicate your problem.
 * Please try the latest version, v2.0.1, that i released today and see if you still
   have issues.
