I am using an active-X toolbar in my LabVIEW 7.0 application. A callback vi is used to trigger a dynamic value change event which is registered to a control on my front panel, (when a button on the toolbar is pressed, the callback vi picks it up and writes the button value to a value (signaling) property node which is referenced to a control on the main front panel. A value change event for that control is picked up in the main vi and the proper action takes place). This all works fine when I run it locally. My problem is that this event is not generated when I use the web server to publish the front panel to a web page, then go to that web page using Internet Explorer and try to interact with the vi using the toolbar. All other events work as they should - everything but the dynamic events. Any help would be greatly appreciated.
