LSP is crashing for you in the Visualizer? What are your PC Specs? I'm running an I7 with 8 gigs of RAM on a 64bit system and haven't had a problem.
Just running a windows 7, i7, laptop for playing with a 500gb ssd, and a little light on the ram. Maybe with black friday will pick up as big a set of chips as will go in a E6530.
I think you could duplicate it. I drew 4 arches from four different ssc's on the visulizer. Now try to select one of them after it's drawn and you toss an error on the screen. Persist at it and don't click abort or one of those and you can blow out completely.
I have taken to drawing a couple of items, saving, saving the sequence and then exiting, re-opening and continuing with other tasks. I don't mind at the moment as I am totally lost in there still and just happy my wife and I figured out most of the non RGB items that will be on display this year so I can draw some of them in.
Are there things like candy canes and big bulbs to put in there?
