I am running Hog 3PC V3 on my vista laptop and the DMX Output screen is blank. I am just editing a show so there are no widgets connected. I seem to remember it working without things being connected in the past. Any ideas?
You need to have a widget or DP attached and some fixtures patched for any values to show up in H3PC.
The Output window constantly refreshes the actual output by communicating with the output device. If you have no output device there is nothing to communicate with.
