My team and I have recently started using JIRA and all is going smoothly until I found this problem.
On our Kanban board if we change the status of an issue from the dialogue box within an issue workflow screen e.g:

The next workflow screen shows up for the user to add a comment but the fields can't be clicked, they are greyed out, e.g:

However if we drag the issue from one column to the next within the Kanban board it allows us to edit the workflow screen.
