Question : Windows Vista - Multiple Email Signatures

I have two email accounts in windows mail on Vista.
I have setup two signatures, one for use with each account, one of them is a default.
When I try and create a new email, the default email address is used with it's default signature.
If I try and swap the email address to be used in teh From field, the signature does not get changed (I would expect that).
The only way that I can see to use the correct signature on each account is to change my default email address every time I create a new email - this can't be the only solution?

I found another question on EE with an accepted solution, but I don't think this solved the same problem that I have? Sounds like the same problem exists in outlook express.

Answer : Windows Vista - Multiple Email Signatures

After a lot of googling I found that there is a insert button you can add to the toolbar that will insert the sig attached to the email account. Also, inside this link the discuss that windows live mail does the automatically for you.
