Help: Map Keeps Jumping When I try to Align It

I'm trying to align a hex map, but whenever I try to move the map so I have any hexes lined up so I can size them, it jumps off the alignment I've set. It's really getting frustrating because I just can't get the grid on the map lined up with the virtual tabletop.

Thanks in advance.

It is probably clicking to the square grid of the page.  You have 2 options:

Option 1

Hold the Alt key when you move the map around with the mouse so it does not click to grid.

Option 2

Right click on the map.  Choose Advanced--make drawing.  A drawing does not click to the grid.
