That worked thanks!
This wasn't happening before I upgraded my computer. Is skitch compatible with the new mac system? Anytime I try to take a screenshot, the image does not capture what's on my screen - it takes a screenshot of my desktop background instead. I've tested this on my computer and my colleagues' and can confirm it's only happening to Macs that upgraded to the new Catalina system. Please advise as Skitch is rendering useless right now.
