I know you have made a stuck jiffies post in the past. So, I am reluctant to say load Beta 13 because you may be running a version of Hijack that fixed your past problem. But, from what I gather, it sounds like you have the stuck jiffies.

If you recently loaded a newer version of Hijack, I think post-Beta13 have the jiffies fix removed due to it being addressed in Beta13. I never had the jiffies and don't run Hijack, so I may be speaking out my ass.
