Since upgrading a project to use latest version of B4J I now encounter this error when clicking a particular button a second time.

Unexpected event (missing RaiseSynchronousEvents): donebutton_mouseclicked

Odd that all the other buttons work fine, just this one generates the error. It calls a print routine via javaobject.

Found the problem - as I am using java 8, the new security measures block access to the system printers.
After I signed the jar file, it works fine now.
(It was working in the IDE, but as a stand alone it needed signing to work properly)
