Pat,

This is a very good question. Unfortunately, we cannot do this with the
unsigned/untrusted JmolApplet.

Accessing the local system clipboard was considered a potential security
violation. Therefore, an untrusted applet cannot access the local
clipboard when running in the secure applet sandbox.

A =22poor man's substitute=22 would be for you to have a textarea in your=
 HTML
page where you could paste your MOL file. You could then press a button t=
o
load the contents of that textarea into the JmolApplet.

Since we are on the subject of security, there are two other restrictions=

that are worth pointing out.

 - An unsigned applet cannot read files from the local file system. This
means that we cannot let users load .pdb files from their local system.

 - An unsigned applet cannot load files from a web server other than the
one it was loaded from. This means that the applet cannot load files
directly from the PDB.

I am hoping/planning to release a signed/trusted Jmol applet in the
future, which may be more appropriate for some applications.

I now realize that you were probably asking about the Jmol application
instead of the JmolApplet.

Yes=21 Good suggestion=21
