Hi I noticed that I get different behavior with highlight-regexp in emacs 24.1.1 than in 23. Loading the file below, the text that is in the file when it loads will be highlighted in the correct color, but typing new text will not highlight. In the previous version the highlighting would update dynamically as you type. This is the windows version running under exactly the same environment. If I switch back to 23 it's fine. FILE START A test of colour syntax highlighting When I type yellow it should go yellow, and green goes green // This enables custom syntax highlighting // Local Variables: // eval: (progn (highlight-regexp "yellow" 'hi-yellow) (highlight-regexp "red" 'hi-red-b) (highlight-regexp "green" 'hi-green) (highlight-regexp "blue" 'hi-blue-b)) // end: FILE END If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'.
