I always have some problems with that function! But this time it's a disaster!!
The window is every time too much high and I can't reach the button at the bottom but this time I succeed to reduce it and I click on play to go back in my game. And it's the announcement "do you want to restart the game" that appears! I want to say "cancel" but nothing arrives, so I decide to close the game. When I open it again, I can see that it has restart!!! I loose my favourite, loved tribe!!!
And now, impossible to reduce the window! Finally, in reducing the bar at the bottom of my screen, I succeed to reach the options and to go back in full screen! And now I have a headache!
I delete my last tribe because it's too late in the evening to start a new one. but it's the last time that I change the "fullscreen"!!!

i didn't reall understand what you are talking about...But reamber to backup your game!:)

My full screen off/on button works perfectly i cannot see how clicking one simple thing can cause your game to restart!!!

Did you back-up your game before this happened?

I have only just noticed this topic is a month old

I should think not! I did not back-up my game (in fact I don't know how to do! ) I think that I have a problem of regulation of the dimensions of my screen. (I have a new computer since a few month!) For the moment, I play in full screen and I'm used of.
As you said, it's a month old and forgotten now. Thanks for your advises
Ps: Lailai, what that means "reamber"? I don't find it.

In the future if you need to backup and recover your game files you can do so by reading This Post.

She was ment to put "remember"

Thanks a lot!! I have to learn again the "forum language"

As a former teacher, I can't resist:

"She meant to put remember."

LOL! All the same!!! (my parents were teachers too!)
