The issue is that the middle mouse shortcut for increasing parameters by 0.1, 1, 10 etc gets stuck on the screen. I’ve tried everything to get rid of it, even deleting the operator and recreating it, but nothing works. It can be incredibly infuriating.
I know this used to be a common issue, but I haven’t personally had it happen in 2025 versions of TD. Which builds are you running out of curiosity?
One thing that used to clear it for me would be to minimize the TD window to the task bar and then reopen it.
