The OrbVis FAQ

These are the system requirements

Win 9x/NT: Netscape Communicator 4.5 or MS Explorer 4.0 or higher; VRML 2.0 plug-in Cosmoplayer is recommended.
It was reported that WorldView 2.0 does not work.
SGI: Netscape Communicator 4.04 with JDK1.1 patch, Netscape Communicator 4.06, 4.07 or 4.08;  VRML 2.0 plug-in.
Netscape Communicator 4.5 will not work together with Cosmoplayer 1.1, because of a bug in Cosmoplayer 1.1. In Communicator 4.05 the EAI does not work at all.
Mac: We are unfortunately currently not aware of a setup where our service works.
WorldView 2.0 has a bug and so will not work with Java1.1 in Netscape Communicator. Above that, WorldView for Macs is not longer be supported by Intervista/Platinum.

I get a message "No VRML Browser access - press shift-reload" in the Java-Applet or in a window

If you are using Communicator 4.04 press "Shift-Reload". Due a bug in the External Authoring Interface EAI the access to the VRML plug-in only works when the applet is reloaded.

Even if I press "Shift-Reload" I get the message "No VRML Browser access - press shift-reload"

Try to open a second Browser windows and load OrbVis into this window. This seems to be another strange bug in Netscape Communicator.

There are some strange effects with MS IE 4.0.

The problem is that MS IE does not support dynamic window targetting depending on the outcome of some remote computation. When using Netscape, the results of a query are either sent to the status line (if there is a problem) or the molecular orbital page (resulting MOs). The destination window is encoded in the MIME header of the response. MS IE simply ignores this information. All window targets must be predefined in hyperlink anchors and query forms. So, currently all immediate calculation results are sent to the structure source page if you use IE, regardless whether this is an error message or the result of the MO calculation.

The structure that I created with the editor is not the structure which is displayed

You can create structures with the editor even when they make no sense. Our service employs some semi-intelligent mechanisms to correct structures which contain certain types of problems.
