Hi
Lightoom V3 installed on an iMac and a MacBookPro. All works as should on the MBP. However, on the iMac I cannot edit at all. I click on the edit buttons and tools show, but the sliders have no effect. No gradiets show up. The cursor moves but nothing happens on the image. Can't click Auto or B&W, nothing on the image changes. This is true of every tool. Another oddity: the I select 'Show Histogram' and the panel drops but the histogram doesn't show, all I get is blank space.
If I click on the crop/rotate tool the image just disappears and I'm left looking at a blank panel.
If I edit an image on the MBP the edited version shows up on the iMac. They are both on Catalina, latest version.
I've reinstalled, I've logged out and back in, I've trashed preferences. Any suggestions?
Thanks
