Hi, I use an iMac (an older machine) running Mac OS Big Sur 11.6.8 when working from home. Skitch works as it always has - perfectly. When working in the office or from a client office, I use a MacBook Pro running Monterrey 12.5 - Skitch will not launch. I get the report an error screen and before I can type my name it crashes too. I've uninstalled, reinstalled, rebooted a million times and checked all the settings and I can't see anything wrong. Anyone else having issues with Skitch on Monterrey? Any fixes out there? I tried to get a screenshot, but this is all I could capture before it crashed out again. I've been using Skitch for many years, but now can't even get it to take one screenshot. Thanks! DHT
