but you also need to make sure that Cookie is NOT listed as a Login Item in System Preferences > Users & Groups
Thanks Russell. That was the trick! Problem solved.
L-O-V-E Cookie5. I wish I would have found it years ago!
Running Cookie5 with Mojave and previously High Sierra without problem. Recently received 5.9.2 via the Mac App Store as an update, and now the Cookie5 UI appears every time I login to macOS when Cookie5 is launched. I still have both "At Login" preferences checked (Open Cookie & Hide at Login) as I did before this recent update, but the hide option does not appear to be working any longer.
Is this a bug or something you can suggest to put Cookie5 in the background at start-up once again? THANK YOU for a GREAT product.
