Hi Mike-

Thanks for this.

That sounds strange- I'll let the systems guys take that. To confirm,  
webadmin connects and works (so server is up) but insight and  
importer do not connect?

The phenotype you describe is expected-- JBOSS does not like sleep.   
It doesn't like network changes (e.g., disconnecting network  
connection).  But no worries, the DB should be just fine.  I've made  
a similar mistake with my own machine-- and yes, things are then no  
good at all.  We've built OMERO assuming your server will stay up.  
Try to kill the JBOSS process, and then restart it.  I've done this  
previously, and never had a problem.

You obviously want to run the whole system on your laptop.  We have  
talked about building a specific version for this, but haven't done  
it yet.  From a developer's point of view, your approach should "just  
work".  Let us know if this is a strong requirement and we will look  
into it.  We just didn't feel like competing with Aperture  ;-)!

Hope that helps.

Cheers,

Jason
