Hello, I think I am having the same issue with the latest update. I have tried the default Ctr + N and Ctr + enter and neither brings up the window anymore. Before the latest update the mod worked fine and I have tried disabling all other mods and starting a new game and it still does not bring up the window showing input/output info. The curser shows the typical yellow icon but no window appears after selecting objects.
Edit: I am now noticing my measuring mod no longer brings up the necessary window, could be a problem with the latest build?
