Esnap not snaping to where I want it

I am having trouble with Esnap snaping to where I want it. For example I want to drag a line to an existing line. I click the end I want to drag and then pull it over. Draftsight will highlight the end of the line I now want to snap and I click. But when I zoom in the line is not touching and didn't snap. This is driving me nuts as the same thing is happening with dimensioning. It isn't snaping to the exact point so I am getting "wrong numbers" it is drawn correctly but at first glance since it isnt snapping and dimensioned properly I get "wrong numbers". I have done a quick search and turned off Etracking, and I am still having this problem.

I see from searches I am not the only one who is having this problem. I went back to some of my first drawings (been using this for about a month on and off) and I'm noticing it has been happening since the start. Is there any solutions to this?
