Hello,
i have a problem with my putty session when i use the vi editor or i do dbaccess on an Informix database.
Suddenly the background and foreground colours of my terminal change and it makes it difficult for me to identify whats on the screen.
why this is happening? is there a way to keep my default background and foreground colours when i use the vi editor?

Thank you
