Guys
I've been using Bumpy's calculator for several years on my desktop and really like it. Problem is when I download it for my new Android tablet for portable use. The yellow columns are locked, or at least haven't figured out how to make changes in them. When I tap one it gets a blue outline with the dot in the lower right corner for copy but no keypad comes up for entry. I tried tapping the box and then the menu to see if anything was there, even tried highlighting the whole column and checking the menu. I tried copying the one from my desktop so I would have the custom alloys saved there, but had the same problem.
How do I unlock this thing on the tablet?
Thanks in advance
