How to use Streak 5 via PC

Hello,

A little question.

Happy owner of Dell Streak 5 + Dock HDMI, I found some drawbacks.
It is not very uneasy to use the phone when the device is inserted  to answer short text message for example.

In addition, although the keyboard is large, it is easier to write on the PC keyboard.

Does an utility or driver exists to do it

I had it with my N95 - which allowed, once the phoneconnected, to have a popup on the PC when receiving a text message, and respond directly from the PC, or even access SMS and create from the PC.

Thanks in advence
