Description yacadoo 2012-05-20 22:12:15 UTC
I am not able to add an action in the Signals tab. For example: If you add a simple button in the GUI designer, then go to Signals and then click in the area that says something like "click to add an action" and then type a name for the action and press ENTER an error will popup and no action will be assigned.
