Two questions, first is similar to Message box modal lock focus but this post is not answered.
I have a message to confirm user saving settings. I only have an encoder as input device. But rotating the encoder makes it scroll widgets under the message box.
Second problem is, the close button on top-right and message buttons don’t seem to be on same level, which is confusing. It seems you need to click the encoder after it disappear from the close button(No hint at all!), only then will the message buttons can be selected. Checkout the video below at 00:08, only after the select seem to select nothing, can you be able select buttons.
I dig a little and find the modal message box in V7, tried it but still encoder will select things under message box. (The half transparent background is the obj of screen size)
