These things happen. I'm on 4.0 and wiiflow, i get the same problems.
What people don't understand is that all this wonderful stuff that has been created is always going to be an ongoing process.
The code was not written by N and noone was given the information of the system on a plate. All these programs have been (amazingly) born from code reverse engineered by commited people over thousands of manhours (sorry, personhours).
Anyway my point is why do you want to jepordise your wii just for the sake of a few minor glitches?
Dont move away from the console until the second time you press power, simple fix and no modding required.
