are these forms correct?

All this "thinking" is new, it's temporary, it's current, and it's urgent. In this context, the present progressive works.

Thanks for that. I was trying to come up with some examples, and couldn't think of anything convincing, apart from the slightly different "I am thinking of leaving Prague"and "Be quiet. I am thinking" that I noted earlier.Your example is natural for the sense we are discussing.
