I have this issue on my old windows laptop but not on my mac ;-) I agree this is annoying on my windows laptop but since I do not go so often in that option dialog, it's ok.
I am wondering though if it wouldn't be better to change the UI ? The UI requires to be big because all the "slots" are displayed.
For example, for key mappings or preset mappings, what I needs is just to be able to map 1, 2 or 3 things. So the UI takes a lot of place compared to what I need.
So I am wondering if a UI where components are displayed "as needed" would be much useful ?
