Lightroom Classic Now appearing in all desktops
I am running Lightroom Classic Desktop 10.4, on an Apple Macbook Pro 2 years old, with OS Big Sur 11.5.2.
I run multiple desktops and have done for a while. This week if I run Lightroom Classic it appears on every desktop. It's the same application and if I change one copy it changes on all of them. All hardware and software up to date. Also Photoshop is OK and all other software, only Lightroom Classic. It was working fine now started this, any ideas please tell me.
