Please don't be offended, but I want to describe each step to make sure we don't miss understand each other. I know you already know how to do all this below, but it might be clearer this way.
If you are running bash as your shell (which is likely to be true if you are under Linux)
then your prompt might look like this
[you@yourhost ~]$
at that prompt you would type the following:
export TERM=gnome
press Enter
then at the new prompt
[you@yourhost ~]$
type:
BitchX
press Enter again
when BitchX it comes up things should work better. If it doesn't work, post here again and we'll just think harder.
