UserForm Textbox cannot enter text

Question

Hi

Excel VBA 2016 Pro

I have a userform that has 70 textboxes.

1 to 20 and 51 to 70 are data inputs. 

1 to 20 work perfectly.

51 to 70 do not allow any input at all. They are all enabled=true

I had to write vba keycode, keypress procedures to get them to work. Which works ok.

Is anybody able to tell me what has caused VBA text boxes to be dysfunctional.

Google search was unproductive and no solutions were found..

There was only one that had a similar problem. Solution was of no help to me.

Cheers
