When moving a drawing entity by coordinates in the Page Builder, the first number entered always turns into a letter.
(In Page Builder tab)
Click "Move Drawing Entity".
Click any drawing entity.
When prompted with "Select or enter point to move from", enter a number using the number pad.
The first number entered will always turn into a letter and nothing happens when "0" is pressed.
This only happens when using the number pad, and only happens if you type the number without clicking the entry box.
See attached. In this screenshot, I typed "5,5" but AGI displays "e,5".
