BlackBerry :: Compose From Non Default Account?

I have 2 email accounts, a corp account and an internet account. When I review emails in the internet account and then compose an email, the blackberry now populates the send using field with the default corporate account. That's new behavior of the BIS according to my ATT support contact. I can't go back to the previous behavior where it just populated the send using field with whatever account I was reading at the time. Anyone know of a workaround? It's a pain to change the send using field every time I write an email from my internet account.
