I get RequestProcesso exception when I start the ide. (I can't copy details of the exception because the window is obstructed by the ide. The details look similar to the next exception below. But here are the first few lines: Exception occurred in Request Processor java.lang.IllegalStateException:Duplicate pairt in treePair1: SL[/Browsers/SwingBrowser pair2:....). When the ide eventually comes up, usually I can compile my app. But when I try and deploy and run it, I get another exception - IllegalStateException see details below. At this point my only option is to remove the .netbeans folder and recreate my project. Details of the second exception, and log file: java.lang.IllegalStateException: Duplicate pair in treePair1: SL[/Browsers/SwingBrowser pair2: SL[/Browsers/SwingBrowser index1: 6 index2: 6 item1: org.netbeans.core.ui.SwingBrowser@955b34 item2: org.netbeans.core.ui.SwingBrowser@955b34 id1: 1ddad02 id2: 196b753 at org.openide.util.lookup.ALPairComparator.compare(ALPairComparator.java:52) at java.util.TreeMap.compare(TreeMap.java:1085) at java.util.TreeMap.put(TreeMap.java:463) at java.util.TreeSet.add(TreeSet.java:209) at org.openide.util.lookup.AbstractLookup$R.initItems(AbstractLookup.java:788) at org.openide.util.lookup.AbstractLookup$R.allItemsWithoutBeforeLookup(AbstractLookup.java:749) at org.openide.util.lookup.AbstractLookup$R.allInstances(AbstractLookup.java:691) at org.openide.util.lookup.ProxyLookup$R.computeResult(ProxyLookup.java:378) at org.openide.util.lookup.ProxyLookup$R.allInstances(ProxyLookup.java:329) at org.openide.util.lookup.ProxyLookup$R.computeResult(ProxyLookup.java:378) at org.openide.util.lookup.ProxyLookup$R.allInstances(ProxyLookup.java:329) at org.netbeans.core.IDESettings.getWWWBrowser(IDESettings.java:345) at org.netbeans.core.NbTopManager$NbBrowser.<init>(NbTopManager.java:613) [catch] at org.netbeans.core.NbTopManager$1.run(NbTopManager.java:328) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:178) at java.awt.EventQueue.dispatchEvent(EventQueue.java:454) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:151) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:145) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:137) at java.awt.EventDispatchThread.run(EventDispatchThread.java:100) LOG FILE: ------------------------------------------------------------------------------- >Log Session: Friday, December 17, 2004 2:12:18 PM EST >System Info: Product Version = NetBeans IDE Dev (Build 200409220845) Operating System = Windows XP version 5.1 running on x86 Java; VM; Vendor = 1.4.2_04; Java HotSpot(TM) Client VM 1.4.2_04-b05; Sun Microsystems Inc.
