How to prevent xshell from autostarting xbrower when start vim?

Question

I used xshell as a terminal to connect to a remote host, but whenever I start vim, xshell automatically starts a xbrower and tries to "xstart" it, I assume it tries to start gvim or some thing with a xwindow, but this is very annoying, how can I silent xshell and make it do what I have told it to do? Thanks.
