Lost header on Thunderbird

[Monkeyman]

Somehow, I've lost the top header on Thunderbird.  This is the one that has the maximize/minimize/exit icons.  Not sure what I did so I'm not sure how to fix it.  I keep the taskbar hidden.  I can't pull the taskbar up when I run my cursor to the bottom of the screen like I can with any other window open.

I feel stupid asking but can someone sort this, please?

Thanks.

Well....never frickin' mind.  I did Alt-Space to minimize the window and got the header back.  Um, odd and sorry to waste the sites bandwidth.

There are no stupid (genuine) questions. Only stupid answers.

Am sure at some stage someone else will benefit from what you've learnt and just shared.
