Well, apparently when I installed version 69 of HiFi, it must have uninstalled at least some part of Sandbox, but left the auto-launch-at-startup thing intact for it. I’m not really sure if I should go thru and manually remove whatever that is (and if so, how would I go about it?) or install the new Sandbox.
Ideally there needs to be offered a choice at install time for the new versions of HiFi as to whether a body wants to install just the Interface and its related bits and bobs, or if you optionally want to install the Domain stuff. If you choose to update the Interface but not install the Sandbox stuff, then it should check to see if there was a previous version of Sandbox there and if so, ask if you want that removed, or simply deactivated (i.e. remove the bit that does the auto-launch-at-startup).
I suspect my best bet at this point, at least for the time being, is to turn off the auto-launch thing, but I’m not sure how to do that exactly.
