Looks like there is a bug in the rights surrounding Waiting Lists.

I give my users the following:

• Add Clients to Waiting Lists 

• Display Client in Waiting List

• Edit Clients in Wating Lists (

• Front Desk List

• List of Clients in a Waiting List

• List of Waiting Lists

And from the Client - Waiting List, this is what they can see:

In other words, they can Display Client in Waiting List and click the Manage Clients button (whatever right that is), but not Edit Clients in Waiting Lists.  There should be an edit button here.

If I give the user the additional permission:

• Edit Waiting List Records

They see the extra edit button on the Client - Waiting List:

So the Edit Button on the Client - Waiting List seems to be tied to the "Edit Waiting List Record" right, but it should be tied to "Edit Clients in Waiting Lists"
