I have Poseidon 4.5. From what I recall I updated from 4.4 when I got my RapidRoad. It wasn't much of a change, just a few classes and hardware drivers, more than anything, from what I recall.
For what it's worth, PoPo is started by PsdStackloader
Specifically, the command should be in your S:User-Startup file, as:
ENVARC:PsdStackloader
I confirm that commenting that command out kills the "PoPo" commodity on reboot.
I swear there was a setting for stack size somewhere within Prefs:Trident preferences program, but I'll be damned if I can find that now.
Will try to poke around a little more for you but am buried at work right now. In any case, I wouldn't recommend rolling back to 4.4 - 4.5 does work!
