Accidental Adjustment of Column With in Editor

I am in and out of the Editor a few times each day tweaking, changing, checking. In the Editor when you click and hold anywhere and move the mouse it automatically slides and adjusts the width of whatever column the mouse pointer is in. This is a most unwanted behavior for me. It seems I am always somehow accidentally clicking and holding for even a brief second and them my columns are all goofed up and I need to fix the widths.

Is there a way to disable this behavior? I have tried for so long just to deal with it, but it is a real annoyance when it happens.

I will look in to it, it is probably my fault, so hopefully I can correct it in a future version (but probably not until the next major version now).
