Thanks,
so what does MEX actually stand for? I assumed it related to matlab mex 
files so hadn't checked into it.

Are there some examples anywhere?

We are mostly writing imagePro scripts, so we can save this information 
in any form we like. I'll look into the data type.

I tried to install from scratch but obviously didn't do enough. Is 
dropping the database, removing the installation (/OME/) heirarchy and 
the /etc/ome-store file enough to constitute a fresh install? What else 
is necessary.

Alternatively, are there cvs tags or branches that allow me to retrieve 
a "latest" version. I've only seen "stable" and "current" on the web 
site. I've installed current (as a fresh install if the above is 
sufficient), but seem to have problems with thumbnails and serving images.


Thanks again.
