There is a known problem with the Thieme Pharmaceutical Substances Structure Query function. The error messages differ based on your browser. In Internet Explorer: Application Blocked by Java Security. In Chrome: This plugin is not supported. Thieme is aware of the problem and it will be fixed with the next version, scheduled for release early next year.

In the meantime, there is a workaround for Internet Explorer, but you must manually add it to the Java Security Exception Site list:

1. Go to Control Panel > Java > Security
2. Click “Edit Site List…”
3. Click “Add”
4. Type http://pharmaceutical-substances.thieme.com/prod/ in the Location field
5. Click “OK”
6. Click “Continue”
7. Click “OK and “OK” again to exit the Java Control Panel and save the changes

There is no work around for Chrome.
