I can't move the divider between the code and plot panes in versions 2.06 and 2.07. I can move the divider in version 2.04.
On my computer, the code and plot panes are roughly equal in width. If I position the mouse very carefully there is a 1 pixel wide area where the resize cursor appears, but I can't move the divider.
Is this an intentional change or a bug?
