That code suggests to me that you're not removing the listeners properly. The previous instances of the frames are still there in memory with listeners on the query data set. Managing listeners whose sources survive the destruction of the destinations can be quite tricky. Make sure you're using "remove..Listener" when closing your dependent frame. -- Kevin Dean [TeamB] Dolphin Data Development Ltd. http://www.datadevelopment.com/ NEW WHITEPAPERS Team Development with JBuilder and Borland Enterprise Server Securing Borland Enterprise Server http://www.datadevelopment.com/papers/index.html Please see Borland's newsgroup guidelines at http://info.borland.com/newsgroups/guide.html
