Default C::B perspective annoying dialog

[Manolo]

I use C::B nightty 10912, but I remember this since always.

Start C::B, don't do anything else. Close C::B. The dialog with "The perspective 'Code::Blocks default' has changed. Do you want to save it?" appears.
I ask myself, What do I have different that always changes the perspective? The editor colors? Some option, I don't remember which?

Thanks

What I do is adjust the size of the window frames.
That of the editor frame relative to the log frame.

"The size of the windows frames".
OK. Saving that new "default" makes the dialog doesn't appear anymore.
Thanks.
