This release handles a recent change in the popup window that was the subject of release 3.11.0. IBKR have changed that dialog box in a way that prevents IBC from recognising it. See issue #142 for more info.
IBC will now recognise both the original version and the new version (it's not known if the original version will still appear at all, but if it does IBC will handle it).
All you need to do is replace the IBC.jar and version files in your current IBC setup. You can get them either from the installation zip, or directly from here: https://github.com/IbcAlpha/IBC/tree/master/resources
