I have a problem when I want to focus on a particular text box. I’ve created a tab with a single text box. It has a lot of text, so I’ve allowed a scroll bar. The problem is, the focus doesn’t stay on the text box. Initially, when trying to scroll, the whole window tries to move around. I have to make a conscious effort to click in the box before scrolling. It’s very irritating. It would be better, once I’ve clicked on the tab, to be able to scroll to the part I need.
I've attached a video to illustrate my problem. (Disregard the layout .... I'll tidy it up once I get this working).
