[Chimera-users] Surface picking

Hi Prit,

  I can select the split surface pieces of an MSMS surface with ctrl-click using Chimera 1.12.  Does ctrl-click work to select atoms, or the original unsplit surface?  If not then it is probably a graphics driver problem, since some graphics capabilities are needed to know what object is under the mouse.  Another possible graphics driver problem is the green outline is not shown — but if you select something the magnifying glass icon in the lower right corner of the main Chimera window (select inspector) should turn green.

I can display the MSMS surface and split it into pieces (accelerator Sc), but then I need to select the extra surfaces to hide/delete them (starting with the main outer surface). For some reason surface picking with mouse (Ctrl + left click) doesn’t work. I checked the surface attributes and ‘selectable with mouse’ was true.
