I decided my issue. I removed the code from the file. (as was the case
previously in 2.5.2). The problem disappeared! Make it please in the next
version.
LineSegmentIntersector.cpp
removed the code from the file: line 290 ..
double epsilon = 1e-8;
if ((s-e).length()<epsilon)
{
osg::Vec3d delta_e_end = _end - e;
osg::Vec3d delta_s_start = _start - s;
double scale = 0.001;
s += (delta_s_start * scale);
e += (delta_e_end * scale);
}
code version 2.5.2:
s = _start;
e = _end;
The problem disappeared! Make it please in the next version.

> Here is the small example, where described problem appeares. Example is
modified example of osgpick (chenged code which returns name of object and osg
scene). To see this problem you must go in the deep of room (way is showen in
00.jpeg). Then you need make several clicks in different positions (movements
bitween positions must be small) and you will see that cursor often falls
throught the object over which cursor is (possible positions is showen on
11.jpg). There is two archives in attachement (with textures and without them).
Code is in osgpick.zip file which taken from example osgpick. I hope this is
enough to illustrate described problem. And I think it will be not good if this
error appeares in this release (2.6.0).

viewer->computeIntersections(x,y, hlist) works very strange - when cursor
movements over object is short it(cursor) falls throught the object and
function returns name of object which is behind current(object over which
cursor is). In earlyer(less 2.5.2) versions of OSG this error has never
appeared. How can I solve this problem in this(2.5.5) version of OSG?
