Description

I found this issue in hg19:

Steps to reproduce:

copy chr5:131800537-131801093 into the coordinate window and click go;

Then the browser shows chr5:131800537-131800982 instead of chr5:131800537-131801093.

I also tried to modify the end coordinate(131801093) and they all go to chr5:131800537-131800982.

See pictures for the browser shot.

Weird.. I just tried on my laptop and still have the same problem but now the coordinate is different again..

Now I see the problem. It is because on a wide zoom level in the browser, one pixel width of the horizontal axis spans a range of basepairs (or a bin). When browser relocates to a coordinate from text input, the landing coordinate may starts from a bin containing the original start, thus comes the small discrepancy. I will try to solve it.
