Any idea what could cause this and how to stop it from happening. Put a breakpoint in the event handler. When the breakpoint is triggered, press the green "Go" arrow at the bottom left to let the program continue running. When the breakpoint is triggered for the second time, look at the "Stack" tab in the debugger to investigate the stack trace. The odds are that you are indirectly calling the event handler recursively, perhaps by modifying the control in some way that is triggering the event a second time. -- 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
