thing is, even in release it will print the error when using it as a console app.
Oh yeah, I didn't notice that.
I usually create my own custom error notification system for some of my larger projects something like this...
Graphics 640,480,0,0 OnEnd(Cleanup) Print "doing error" 'If True Then RuntimeError("error! oh no!") Error("error! oh no!") Print "done error, should never print this" 'and doesn't WaitKey() Function Error(Msg:String) Notify(Msg,True) End End Function Function cleanup() Print "cleanup" End Function
Anyway thats beside the point, RuntimeError *should* work in release.
Note: That example is basically replicating RuntimeError.
