Drag and Drop Messages on DropFailure

Hi All.

First post and a freshie, so please be kind.  That said I have had some experience in other coding disciplines so I am not too dumb.

I am trying to create a drag and drop which gives feedback on a 'dropsuccess' and a 'dropfail', here is the scenario. 

I have two targets a 'bin' and a 'safe'.

I have 6 sources, 4 are 'bad passwords' and 2 are 'good passwords'.

The idea is that if the user drops a bad password in the bin or a good password on the safe (i.e. a drop success) they get a message as to why it was the correct thing to do.  I manage this by changing the state of a multi state object 'Feedback text box' to provide feedback and as the feedback may take some time to read then this stays on the screen until another password is dropped.

I want to also provide feedback when the user drops a good password into the bin (i.e. a drop failure) but I cannot figure a way to this for any significant period of time.  I have tried the 'Display ... On Reject' but this feedback disapears very quickly.

I am reading about Multi state drop targets (I am using Captivate 9) but can't seem to find any information on how these can be set up or might work.

Any advice on any possible solution.

Mark.
