Code::Blocks message upon exiting

[PsychadelicGumballMachine]

I am new to codeblocks and I see this message when i exit the program:

The perspective 'Code::Blocks default' has changed. Do you want to save it?

What does this mean?  I have always answered no because I am hesitant to change something that would make it not work potentially.

The position and size of the frames inside windows are collected in the so called "perspective"
After you changed the size of a window on closing codeblocks asks you to save the changes, so when you open codeblocks the next time the windows are like when you closed it.

You can save and load perspectives with the menu View->Prespective

Ah, ok.  Thank you for the explanation.
