Zaltys, You’re exactly right. I was having troubles wit lots of things until I did away for combination commands for key functions In other words, make TMS up, for example, Home instead of Control+Home
It’s no problem to use key combos with SST - you just have to use advanced commands which is a bit more of a pain to set up initially. If you program the command in both the press and release sections like in the attached pic it’ll work fine. You have to reverse the order in the release section and it should be the actual release of the button here. This works fine for me with my X-55 which uses basically the same SST software as the X-52. If I didn’t follow this approach I was having issues.
