So I had downloaded the trail for LS 3, and starting having some issues.
I discovered that Little Snitch 3 is incompatible with Suitcase Fusion 4. It prevents it from running, with Suitcase giving the errors that it either can't find FMCore or your Font Vault. Turning off LS fixed it. Suitcase works fine with LittleSnitch 2.5.4.
Little Snitch 3 also causes 1Password to say: "1Password Helper is Not Connected". Once again disabling it, or using 2.5.4 fixes it.
I was also having some other weird problems, like MS Outlook taking a long time to launch, and being unresponsive when searching for mail, and those problems went away.
