Me too - this is such a time waster.  I import my invoice descriptions from Intervals Online, and it names everything "Services".  If the drop-down menu on the product/service worked right, it would take a couple of seconds to do each invoice. The way it is now takes me an hour for each one.  

Why have a drop down menu if it does this?  I don't use the automated description feature because I have to customize each invoice.  This has been endlessly annoying.

In fact, the customer service people I have spoken with at Quickbooks agree that this is not good.

In addition, the programs that are not online do allow this.
