Just to clarify - do you mean that the icon disappears (or is not able to be selected) or that it does not work?
Were you able to get the graphics to work correctly?
If you still need help, just let us know and we would be happy to work with you.
I just wanted to follow-up to see if you still needed any help with this problem.
If so, are you seeing this behavior in both your online and offline sessions of ChemStation? This could potentially be a corruption in either the config.reg (online) or conf_off.reg (offline) files if you are not seeing this problem in both online and offline sessions.
Screen captures would also be a great help.
