Maybe in the next upgrade it will be able to handle 8,000 layers. For now, it is crashing off of less than 150 layers with no settings turned on, and I am on a top of the line MacBook Pro with all my memory streamlined, and a massive hard drive slaved to it. MAKE SURE YOU PURCHASE ALL YOUR APPS ON THE SAME EMAIL or you will be in a double nightmare on the new 10 upgrade. I am told this cannot be fixed. What does that really mean? Will it even work right if I delete the one app purchased on the wrong email and buy it all over again? If so, how do I get that synced to my iPad when that app identifies me based on my Apple ID email. There seem to be many oversights regarding this 10 upgrade, which seems like a rough move to happen around the same time the software got restored to its standard pricing.
