Hi Rodney -
Thanks for the suggestion.
UAC is often a problem during development. NCrunch itself is developed on a system with UAC enabled for just this reason - stuff tends to go haywire unexpectedly when it hasn't been fully tested with the extra security constraints.
Unfortunately setting up a feature like this is immensely challenging because it makes the NCrunch runtime environment much more complex. Windows security is very configurable and this would give rise to far more unexpected environment-specific problems that would make this feature difficult to troubleshoot. I have to say that the time spent trying to perfect such a feature would far outweigh the benefits (for example, it would require less effort to make the engine run 20% faster). The need to click the elevation dialog would also mean that this feature couldn't be used for continuous testing (which is the primary purpose of NCrunch), making the feature somewhat out of the current development plan.
Cheers,
Remco
