Yesterday evening I was "hacking" a little script I needed and, since I were bit tired in the end, I accidentally selected "don't warn me when closing multible tabs" -option. So now I can easily close all tabs without warning on konsole. How can I revert this change?

I couldn't find anything suitable in settings or in settings files (neither in ~/.kde/share/config/konsolerc or ~/.kde/share/apps/konsole).

Another file to check would be kdeglobals.

Thanks for answer.

It helped to change option [Notification Messages]: CloseAllTabs=true to false in file konsolerc. Instead of closing all tabs when clicking the "close button" (ie. X) it closes only current tab. This is the option the notification message asks when it pops out. Apparently you can't change this option anywhere in program.

Regarding original problem...
When I deleted konsolerc, the original message returned. So I compared the original with newly created. The new lacked above mentioned option. So I tested deleting only those lines and it worked. I could keep my original file (I wasn't sure if that actually contained anything important).

So thanks for help bcooksley. I now consider the case closed but if anybody has any comments on topic feel free to continue.
