On your first item, you found a bug. I have corrected the problem in the code and will release it with the next update (likely 1.8.4).
On your second point, I haven't done this yet as Windows 8 has not released and I don't know yet if they will be enhancing the base COM library or what the final UI will look like on the RTM Windows 8 Task Scheduler MMC. Once I know both those things, I will update the library.
