Problem pasting into MSketchPane

Using JChem 5.2.04 in a desktop application, most of us have no problem pasting a smiles string into a SketchPane.  But one developer gets this whenever he tries:

We solved this problem.  It turned out that the developer had a partial installation of JChem on his machine.  We used http://www.nirsoft.net/utils/registered_dll_view.html to locate the dll registration data and then delete it from the registry.

Dear Ryan,

we are glad this could be solved and apologies for not responding any sooner.

Kind regards,
Judit
