What's Wrong?

Claude Desktop app message window is overflowing. If text is more than screen size, it should be displayed inside scrollable window. When a chat or any process is in progress and an user input alert window is displayed with large lines of content exceeding screen size, the response options gets hidden below the screen. There is no option to scroll and validate the input options.

To fix this, set the message text control to scrollable and max height to be less than 75% of screen size. So when the content exceeds displayable area, it is displayed as scrollable text and the user input options are visible.
