Disable mouseover event for cells and labels while dragging the minimap #219

Noticed this interesting behavior today while I was dragging the shaded area in the mini map. If I the mouse is pressed while dragging and the crosshairs will be triggered when you drag randomly over the grid cells or labels. This also happened to the scrollbars dragging.

It turned out that the random dragging (minimap, scrollbars) only triggers the appearance of crosshairs when the mouse also hover overs the grid cells and labels during dragging. Luckily, I only needed to remove those crosshairs during dragging.
