Record Store help!!!!!

Question

When I delete a record store I find that I have to quit the midlet application completely and then re-enter it before the midlet recognises that the record store has been deleted. What im saying is that the record store is where the data for a list of names is retrieved from. When i delete the record store and take a look at the name listing I still find the list is populated with the deleted record store names??? Its only when i exit the midlet and the re-enter it that i find the name listing is properly updated i.e. not displaying any names.
Can you please tell me, anybody, why this is and is there a way that i can reset the midlet so that it recognises the change in the record store when it is deleted without having to exit the midlet.
Thanks.

Sure here you go,

So you can see that a player is added to the record store, but when i try and take a look at a list of players that I have constructed the player just added is not present??? Its only when I exit the MIDlet completely and then re-enter it that the player list is fully updated with the new player.
