[chimerax-users] Placement of markers after translation

[Tom Goddard]

Hi Helge,

  That is a bug.  Placing a marker in a map with the mouse should put it where you clicked the mouse even when the marker set has been moved relative to the map.  I will fix it in tonight's ChimeraX daily build.  Thanks for reporting the problem.

Therefore, to move markers, I have to use the "move marker" command on each marker separately. I would like to know if this behaviour is intented and if it can be switched somehow to place markers at the cursorposition even after translation of the markerset.
