Don't bother trying to post code that contains any kind of mouse event. Bravenet's forum software will strip out any mouse event references. There are several other code references that are not allowed. A preview of your post will tell you what will, and will not, render correctly.
Even with code that does post correctly, posting a snippet is usually not worth the trouble. The code itself may be fine, but the code around it may be the cause of the problem. The best way to get help is to create a test page that shows the problem, and then provide us with a link.
