I inserted a Wait, execution delay, in a script and set the delay to 4000 msec.  Saved it.  It seemed to be set to 4000msec.  The script ran the delay for 1000 msec and the that is what the delay was set for after the run.
I tried to inssert 4 different 1000 msec waits next to each other.  Again they save appeared to work.  However, all but one were ignored during the run and they were removed from the script when it was checkd after the run.
Need more than 1000msec available and need to be able to stack more than one delay next to another.
