When cursor is in an eMail field ("To" "CC"), if select  an eMail address from the drop-down list of eMail addresses using my down-arrow key and pressing Enter, the cursor stays in the field and I can continue to type in addresses; however, if I select an address from the drop-down list with my mouse, then the cursor either disappears or drops into the field below where it should stay in the same field for me to continue to enter more addresses.  Both annoying and inconsistent behavior.  Cursor should stay in the same field.

Thanks,

Todd
