Cursor/Insertion point is invisible when navigating with arrow keys.
Recreate by making a field with text in it, and then use the arrow keys to move your cursor to different positions.
The initial state of the cursor is "off", so each time you move it you see nothing, which means you have no visual feedback as to where your cursor position is while you move it. You have to stop and wait for the first blink, which is contrary to how it works in all other software, on every OS, since the dawn of computers.
Please help and thank you.
