The reason for counting characters is to limit the number of characters... so when the count reaches 400, I put up an alert explaining the user has reached the limit.

However, because I am using onkeypress to count the characters, it still "works" when the Javascript error is up. That then results in the is error in FireFox:

Error: uncaught exception: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIDOMTreeWalker.nextNode]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: chrome://global/content/bindings/button.xml :: fireAccessKeyButton :: line 93" data: no]

My first thought was to trim the message. Didn't work.

My second thought was to kick the cursor out of the text box with blur.
if(size > 400)
{
gID("MESSAGE").value = gID("MESSAGE").value.substring(0,399);
gID("MESSAGE").blur();
alert("During Beta Testing Messages are limited to 400 characters. Your message is "+size+" characters long.");
}

But that doesnt seem to work. Any ideas?

BTW: the PHP does also trims the content - so the issue is just the UI and Javascript error, not the function.
