I face this often. Suppose I have killed a buffer. And then I go to the "Buffer List" and try to open that buffer.
Emacs throws the error in "Backtrace" debugger window. And then I have to close this. How can I configure Emacs so that the error msgs are not shown in a separate window but in the minibuffer itself?
I am running Emacs: 23.2.1 (i386-mingw-nt6.1.7601)
