hi, but how do I know whether my Cygwin support the mouse or how to make it support.
Best Regards, sun
If it's a Cygwin build, you may need to make sure that Cygwin can get mouse actions (which may need running the gpm daemon, or something) and that Vim has the corresponding feature (such as +mouse_gpm or +mouse_xterm) compiled-in. Best regards, Tony.
