signature issues with windows live mail

After struggling through various help topics on various forums including Microsoft, I managed to produce and save an html document... but couldn't get it to appear on emails.
I have 5 different addresses and only want it on one. So I didn't tick the box (under signatures) which says to add it to every message - and it didn't appear on any.
Under advanced I did tick the box I wanted it to appear on but without ticking 'all' I don't get it on any?

So basically I currently have it on all outgoing messages rather than just on one address... any thoughts?

Thanks,

Confirming it works when adding to every message? You can also add it to individual messages, I know that isn't a fix, but probably an improvement for what you have now.

If you want to manually choose when to include a signature in your message, ensure that the Add signatures to all outgoing messages check box is cleared. Then, when you want to add a signature to a specific message, click the Insert menu in the message window, point to Signature, and then click the signature you want to use.

Hi Stewart, why not have a signature added to all messages automatically. Its much faster to remove it before sending your message than only adding it to the ones you want it included.

You could well be right, I didn't see that it applies to Vista

Still struggling, now I get the text but the X in the box for the image! I tried this link - How-To: Windows Live Mail 2011 Email Signature With Image - YouTube but that didn't change anything.
I actually have Live Mail 2012 now that I've checked, so I don't know if the system has changed again and isn't updated on the web yet?
Anybody??
