I'm running the Designer in an admittedly small window (virtual machine in my case, but it could just be a laptop thing). When the type resolver first displays, the buttons to convert the SQL Symbol are hidden. There is a vertical scroll bar, but when scrolled to the bottom, the buttons are only slightly revealed.

If we could ensure the buttons would be completely visible by either scrolling or resizing the bottom section of the dialog (can't; it's all fixed), it would make for a better user experience.

Screenshot attached.
