I have a weird issue on my I-Mac (v 10.13.6 High Sierra, 2013 iMac). I generally have multiple desktops open on my computer and if Lightroom is not in the first desktop selecting a different module in LR CC Classic cause my desktop to switch to desktop number one (1). It is more of an annoyance then anything because I tend to reserve desktop 1 for the Safari browser. Thoughts? Suggestions?
I guess you need to manage your usage of Lightroom between the connected monitors. Please refer the below articles for the same.
Actually this is the wrong answer... I'm not using multiple monitors, I'm using multiple desktops. BIG Difference. There is a fix for it and I found it after your reply. Unfortunately the latest upgrade for Lightroom blew that away so I'm trying to find it again...
