Ok, I have just discovered that the problem appears to be related to the fact that I have my timeline on my second monitor. As soon as I move the timeline back to the main computer monitor all the buttons are clickable. Anyone have any idea why this might be happening? It's a real hassle!!!
Most likely problem is that all of the columns you want to see in your timeline are not selected when you undock the timeline.
Same here. Working with 3 Monitores and no DropDown works without the main Monitor with High Sierra and AFX. Hoped that this issue would be fixed in CC 2018 but still the same Problem. Is there any solution?
Known issue, JW. We're currently working on a fix. Sorry for the inconvenience.
