I just updated to 16.02, and now the (writing) cursor has horrible problems, especially in text groups. Basically, it is erratic or unmoveable.
In a text group, if I move a cursor down by pressing <enter>, it will not move up with the arrow keys, or it disappears and then appears in previous groups. or a new cursor appears in the line above, but the old cursor remains, or ...
In an execution group, it does a lot of the same things, but not quite as erratic.
