I have no issues either, but I only use LC in preparation, not live. (Have used both during rehearsals but not during showtime) Still have to have my first crash on my H4PC.
I have been trying to run both HogPC and LightConverse on the same PC at the same time and I can't see both simultaneously. Am I doing something wrong or do I need a second monitor?
LC will always be on top when in full screen mode. Go to window mode then you can bring up the windows of hog pc But to work efficient I would recommend a second monitor
