How can I increase the pixel count (tolerance) that will invoke sizing handles to make them easier to select and use?

Question

When working with Word tables, re sizing a column's width requires placing the mouse exactly on the line, waiting for the mouse pointer to change to the sizing control, and then you click and drag.  The problem is that the tolerance is so unforgiving
(a few pixels one way or the other) that is rather difficult to get and keep the mouse in exactly the right spot to invoke the sizing handle.  Because the tolerance is so narrow, by the time you click to drag, the handle control often reverts to a regular
mouse pointer because you moved the mouse a pixel, and instead you find yourself highlighting cell content instead of dragging the column width.  And you have to keep repeating this process over and over trial-and-error fashion until you finally get the
sizing handle to display long enough to actually invoke it when clicking.   It is rather frustrating.  My question is this:  Is there a way to increase the tolerance to invoke a sizing handle?  In other words, increase the pixel count slightly,
either side of the line, that will invoke the control for the sizing handle?   Instead of a few pixels, to something much more realistic/functional, like maybe 5 to 7 pixels either side of the line.  This is also a problem when dealing with columns
in Windows Explorer - you find yourself dragging a column instead of re-sizing it because by the time you click the mouse, the sizing control has reverted to a regular mouse pointer - this has long been a source of wasted time and frustration to me.  I'm
hoping there might be a way to change this in the Windows registry.  Thank you.

Cool article, but not relevant.
I did not import from iPhoto nor Aperture.
I have my photos as JPEG files in a folder on my hard drive.
Photos, the app, did not make any duplicates. Rather, it made a giant Resources folder, almost as big as my folder of Image files.
FInder Info confirms the size increase and lost capacity on my hard drive.
But I appreciate the link.  That could certainly give someone the same impression.
