1.5.9 is in and not subject to the slowdowns seen in the development version (not surprisingly because the development version isn't optimized). Looks good so far. THANK YOU.
Big Muscle, may I suggest you provide a development version that's optimized, though still logs. I have three configs in products I build:
Debug - unoptimized, with full instrumentation.
Beta - optimized, but with a lot of instrumentation.
Release - optimized and without debugging instrumentation.
It's just an idea. I wasn't really able to test your pre-release code much, beyond seeing that it actually worked, because the slowdowns made my Win 10 setup too sluggish to use. I'm very happy the optimized version is still snappy as ever.
