Will update you shortly on how stable I find this build.
EDIT1 - It just crashed when i tried to close a project. I had 3 open. Its definately getting there though. A bug I sent Ashley has been fixed in this build even though i dont think he took a look at it. which is good news.
EDIT 2 - Been using for another 30 mins now. I simply love this program. Seems stable at the moment. Only time will tell.
EDIT 3 - I now have an un-runnable program. Yays. Sending to Ashley...
EDIT 4 - Deleted everything in the frame and it still crashes! Woah
