Window not opening using an Owl account

[soufron]

Hi, just installed it but when I am looking at a mail on my main mail account, and then click on the AI button, whether to resume it or whatever, no window appears.

It works with my other mails account.

My mail account is an exchange accout with the Chouette add on.

When I answer a mail and then try to access ThunderAI, then a window open - from the mail composing window.

Any idea?
