SketchPane bug?

I used ViewPane to display a molecule structure. When I edit the structure, I got the sketchpane; in the sketchpane, if I chose edit->preference, I got the following exception. The version should be jchem5.1, the latest one.























Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Hello,





could you please check your version in the Sketch window? Go to Help, About MarvinSKetch, and copy&paste the info from there (version, op. system and java version).





My colleague will reply soon.





regards, Annamaria

We have tested it but we have not found any error.





It may be a configuration problem on your side. Probably, a resource file are missing from your Marvin Beans / JChem directory or an wrong Java version is used.





Can you give more info about your software environment (os type, Java version)?





How did you install Marvin Beans or JChem package?
