Along with breaking the loop click on New button serve one more
purpose. It invokes the append_page() function and if you are going to
change this then you have to think how to invoke this function.

There is no frozen window problem here both windows (i.e. analyzer and
gnucap main terminal) are active. Just once run the code from
AbhinavSingh-WIP without any modification if it works then we will go

Actually i post ponded some works to do in my inter-semester break

Ya sure, but need little time.
