[DUG] Has Windows finished??

[Gary T. Benner]

[Reply]

Jeremy,

The requirement is essentially to know when the resources of the computer are available enough to use ... so just decide what level the "system idle" resource should be ( make it configurable perhaps ), put some hysteresis in there ( maybe 3 seconds ) and you're away. Just keep it simple.

cheers

Gary
