Scale fields in Sprite Editor not accepting numbers

[mitralone]

Hello,

Is anyone experiencing this? When I import new images into my sprite editor, when I try to adjust the scale to be used, I simply can not enter any numbers. I can slide left & right to adjust the value or paste in values but just can not enter numbers. Any ideas or fixes?

PS: It works in the first time the editor is opened but after first number entry, it stops working.
