Hi John,

Would anyone be able to advice where there were any major changes to the API for OMEROcpp between these two versions, and where I might be able to find this information?

Other than the addition of a few methods, there shouldn't be any API changes that would break VolViewer. And as I mentioned, I got the files compiling successfully on 10.6 [1]. What problems are you seeing to make you say it "no longer works"?

I have three different installs of Volviewer running:  The 32bit and 64bit versions that I downloaded the binaries for fromhttp://cmpdartsvr1.cmp.uea.ac.uk/wiki/BanghamLab/index.php/VolViewer#Download and also a version of VolViewer that I built from source using Microsoft Visual Studios 2008.  With all three installs, I am able to open images from either the Omero production server, or from my new Omero Test server.

All three versions of Volviewer that I mentioned previously crash when I attempt to open an image, with the following  message:  “This application has requested the Runtime to terminate it in an unusual way. Please contact the application’s support team for more information.”

Throwing exceptions from an even handler is not supported in Qt.  You must reimplement Qapplication::notify() and catch all exceptions there. “

The build works successfully, but this version also crashes when I attempt to open an image from the upgraded test Omero server.  This version does not issue any errors, but simply crashes and stops responding.
