Problem when posting message using firefox

Hey,

i am getting a problem when using firefox to submit my posts i usally use Alt+S to submit my posts it works fine but the only problem is sometimes even tho i only press it once my post is submitted many times in the thread then i have to delete it manually.

Is anyone else getting this problem and is there a fix for this?

Thanks

 

I've had that problem before aswell. vB's quick reply is pretty buggy at some times.
