I'm experiancing an annoying glitch with Outlook that I have set to automatically roll-up.
I'll click the "New Mail Message" button and the "New Mail Message" window opens and is active. Then when my mouse leaves the Outlook windows it rolls up and becomes active again.
So when I'm replying or starting a new e-mail, the Outlook windows rolls-up, and it's not until I start typing that I realise the Mail Message window doesn't have focus and Outlook is receiving my key presses.
From my testing, Outlook will only steal focus back from it's own windows (New Message, New Task, Address Book etc). It won't steal focus from any other applications when it rolls-up. I'm not sure if this is related to Outlook being one of the application that has a set minimum height.
