Ticket #150 (closed defect: worksforme)

Curtis: here are three errors I found in a log file while cleaning up my home folder this evening. The first one looks like an old 'restore state' problem. The second one hasn't happened in a while. The third still happens on occasion, but seems to have nothing to do with VisBio--in fact, I might have even asked you about it before. Still, I thought I'd file a ticket rather than let anything go to chance.

Got this error starting Visbio rapidly loading sdub; rapidly loading sdub again while first instance still loading
