Hi, Using either Internet Explorer or Firefox is fine. Using Google Chrome can sometimes have issues, though it has improved. The two steps required are:
1. In AmiBroker, go to "Tools | Preferences... | Editor" and make sure that "Copy as HTML" is checked. Then select the code in your AmiBroker editor that you want to paste and do "Edit | Copy". 2. Post using the "Rich Text Editor" from the Yahoo! Groups website. Specifically, click on the Reply button of a post, then when presented with a text editor, click on the link near the top that says "New! Compose your message with Rich Text Editor". Then just paste into the rich text editor (e.g. CTRL+V on Windows).
