No, they do not stay enabled once I enable them, and they change only after the application is closed and then re-opened. I am using version 2010.1.101.0 under Vista in case it helps. Yes I know there is an update and I will install it soon, but I wanted to get my current project working before I applied an update that may break things.
I do silly things during development like, oh, forgetting to put a .drt file in the project folder, or putting illegal codes in the style or input file. I was developing in a rush last night so I don't know if I can remember exactly what I did to get DirectRT to crash, but rest assured it was only when I did something wrong with the settings or input file, I do not expect it to crash in regular use. Of course I would prefer that DirectRT degrade more gracefully in the event of developer errors, so if I can recreate these crashes I will try to keep better notes since I am sure that you would like to work on that.Also - you noted that things tend to crash during development, would it be possible to explain this a bit further?
