Hi Lingwisyer, thank you for your reply. I will check my PC specifications and put them on my signature. I found that my system didn’t like the way my colorbond fences were constructed by me from an invisible wall. I saved the file and created a new one and deleted the fences and that fixed it.
I have a HP Elite 575a from 2012, it was Windows 7 when I bought it and I did a free upgrade to Windows 10 a year ago. It’s a quadcore i7 3.4GH processor with 8GB of ram installed. I will have to check the graphics card though. I ordered another 8GB of ram from Amazon Australia, very good prices BTW.
Edit: Video Card: NVIDIA GeForce GT 530.
