public override void Dispose() throws error after loaded

in Extender Control Base I have this code

[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Design","CA1063:ImplementIDisposableCorrectly", Justification ="Using correct base class implementation and simply setting a flag on the way")]public override void Dispose() {this._isDisposed =true;base.Dispose(); }

After this runs I get an error in ScriptResource.axd

if (typeof(browserHandler) !=='function')throw Error.invalidOperation(Sys.Res.eventHandlerInvalid);

I am using IE 7

[Behaviors: This method releases all unmanaged resources held by the current instance. When theexplicitDisposing parameter istrue, this method releases all resources held by any managed objects referenced by the current instance. This method invokes theDispose() method of each referenced object.]

[Overrides: Override this method to dispose of resources allocated by types derived from WaitHandle. When overridingDispose(Boolean), be careful not to reference objects that have been previously disposed in an earlier call toDispose orClose .Dispose can be called multiple times by other objects. ]
