2.0b1 Header-resize & Mouse-pointer

Alex, this is not a very important issue, but I found that when I assign a small width to a column, the mouse pointer remains in resize mode for a few pixels (right and left the vertical separator) and it is not possible (or difficult) to click inside the column header.
Just for cases like D/C , Y/N or maybe single checkboxes.
Thanks

After a few pixels-style permutation, I get this combination (not perfect, but allows resize and click on small-width columns).

.aw-grid-separator {
    visibility: hidden;
    display: inline-block;
    position: relative;
    overflow: hidden;
    top: 10%;
    left: -11px;
    width: 14px;
    height: 75%;
    margin: 0px -17px 0px 0px;
    vertical-align: top;
    z-index: 1000;
    cursor: e-resize;
}
