Cannot enter pattern for split

Cannot enter pattern for split by nth occurence. Pattern entry field does not allow entry of values.

This is a known issue if you are using a screen resolution with high fonts (high DPI).
You can try to load another skin (in the Environment Options) to see if it solves the problem for you. Or you can paste values from any text editor. Values are actually entered, but not displayed.

This will be fixed in a future update.
