paste problem

Consider a structure such as this one:

<?xml version="1.0" encoding="MacRoman"?>

<cml version="ChemAxon file format v5.10.0, generated by v5.12.3">

<MDocument>

  <MChemicalStruct>

If I draw this structure in MarvinSketch 5.12.3 on my desktop, copy the drawing, and try to paste it into MarvinSketch 5.11.5, nothing happens.  If I try to paste it into the latest version of MarvinSketch 5.12 on your Web site, I get a dialog window that says the format is not recognized, and it asks me to choose a format.  However, if I copy the source code for the structure in MarvinSketch 5.12.3 on my desktop, I can paste it into either MarvinSketch 5.11.5 or MarvinSketch 5.12.  There appears to be a bug in how the data is formatted or characterized when I copy the drawn structure from desktop MarvinSketch 5.12.3.  (Running MacOS 10.7.5.)

Dear Bob!

Thank you for reporting this bug. We will try to solve it as soon as possible.
