When I open any show file and start to make some position with moving heads. It works normally a couple minutes but suddenly it starts lagging.
When I change some lamp position the head is turning but the light stay still. Then menus work but there isn't any text inside.
After a while it crash completely and quit.
The same problem has been approximately one month.
