Inspired by the scenario "pico board" within the documentation site I started a scenario to control the K8055D-Board of Velleman. The board is connected via USB and comes with a fully documentated .dll-file. The concerned uploaded scenario is "GF KD8055". The critical lines are put to comment in the moment. If they are activated it happens that: during compiling it says: no syntax errors; but it doesn`t come to an end and the word "Panel" doesn`t come. Due to this behavior the scenario can not be started. Hi, Michael Berry, or others please help kind regards Yogibear
