Just a quick note for anyone monitoring this thread who hasn't looked in the bugs section recently - we've released an upgrade patch to 7a which (in our experience) appears to totally cure the power up problems. We'd appreciate feedback from people on this before the next release - the upgrade is available at:

Comments about it are probably best put in the bug reports thread, though.
