Dell posted an updated Quickset for the Inspiron 1440. I tested this with the M1730 and all is working fine. This latest version sports a different look to the Volume and Brightness pop-ups.
I have updated the links on the Driver Download pages.
If you are presently running the 9.4.2 version, just download the 9.4.6 and run the installer. You will be prompted to update Quickset, select OK. Enjoy!
