I am adding a tab using the card editor. In trying to set the fields in the edit-box control, I cannot see/access the entirety of the fields and the bottom of the box is chopped off. Am I missing something? I want to add an input formula like what is described here: Multiple Custom Properties into Variable
That properties pane is 'tear off'. You should be able to click-drag on the top of it so it's 'free-floating' and then resize it to see the bottom of it.
If you're working on a server or via remote desktop, I've had to adjust resolution on the machine itself so I could access it.
