Gmail Tasks App logs into incorrect account

[rdh]

Hi there,

For some reason, whenever I create a new Gmail tasks app (using
http://mail.google.com/tasks/ig), Fluid, somehow, uses an older Gmail
account.

I'm logged into my current account in Safari, and have no idea how it
even got the credentials for the old account.

How can I force Fluid to use new login credentials?

Thanks,
Ross
