In Ermine (no longer have Dingo, sorry) there's a way to disable the check for updates. It's in Settings/eDGe Settings/Default Device Preferences. If you really don't want to update, there might be a similar setting in Dingo.
Of course, if you decide to bite the bullet and take your chances, you can just say yes.
The upgrade from that prompt is no muss no fuss . . . unless it turns out you're one of the unlucky ones . . . .
What recourse do people have now if they get the WSoD? Will SupporTrix help? Anybody know?
