is there a way to adjust the sensitivity of the click/drag method of resizing columns?

When i want to manually resize a column, i click the header and drag it wider or narrower. The place to click to do this, though, seems to be about 1 pixel wide, and with a wireless mouse and a high def monitor, it’s really hard to grab the right spot. Can this sensitivity be adjusted?

AFAIK - there is no way.

Maybe you need to adjust the mouse sensitivity. Or it may be a user profile corruption.
