Before upgrading to 4.5.1, I used to be able to move my mouse over my calls in the main page dashlets and a small window would appear to view the details such as the call description.

Now that I did the 4.5.1 upgrade, and also 4.5.1a patch, these pup-up description info are no longer showing.

How can I make them come back?
Is there a file I could copy back from version 4.5.0?

Thanks
Eric.
