Apple Mac Pro (early 2009)
4,1 -> 5,1 Firmware upgraded
macOS 10.14 Mojave Beta 10
TweetDeck web version
I have noticed that in Twitter clients where I need to use the Up arrow key a lot to navigate though a timeline, I occasionally experience a phantom Home key action with the result that the app jumps straight to the top of the timeline without my expecting it. It's really annoying!
This was happening in Twitterrific although I had to stop using it because of problems running it with Mojave. The problem is also occurring in the Web version of TweetDeck (although I have used Fluid to convert it into an application). The fact that this is happening in two separate apps makes me suspect that there is an underlying macOS problem.
Any ideas, anyone?
UPDATE: Thanks for the edit of my equipment list. It looks so much better now!
