New to MB but loving it now only have 2 toons and I'm using Keyclone, and Multiboxer!

I just started last night after reading and reading and reading some more I'm now off questing and grinding.

There's just one problem I have at current. Whenever I type / with my main my alt wants to say part of what I type

EX.

Main types: /dance

Alt says: nce

It's pretty annoying and usually in say where everyone can see it how can I stop this.

And now when i say something in /g both my toons say the same thing pretty annoying and I don't want to annoy anyone as I know how they feel it annoys me!

How can I stop this from happening?
