I have a talking agent on a slide. How can I have her "talk" for 90 seconds and then return to idle automtically? I have tried several methods and can't figure it out

Mark, you can start timer to stop "talking" simultaneosly with calling method. I.e.:

METHOD (agentID, "ACTION", "talk", "wait")
TIMER (90 sec)
- METHOD (agentID, "RETURN TO IDLE")

Note, that the last METHOD is dependable action to TIMER.
