on a empty drawing create 2 circles with radius 13: first on any place, second on command line with "@0,-7.7777" (both have exactly same x-value !).
Now try to "snap Intersection" on the 2 intersection points: nothing will snap.
try out: "move and rotate" these 2 circles together to a new place: snap happens.
a second "move and rotate" with same angle, but other sign: snap don't happen.
Save this in a file, close and reopen: maybe, that snap happens on all intersection points, but sometime not.
This behaviour is not 100% reproducible.
It also occurs on arcs.
I assume a bug in "LC_Quadratic::getIntersection(qf1,qf2)", but i don't understand this mathematic simsalabim.
Please, can one of the experts remove this bug?
Till recently i used a clone from LC1 for my daily work, and so i couldn't detect this bug earlier. In LC1 "getIntersection" was much more simpel, but it worked without such bugs.
