I don't know how your Application runs that scripts, but from your short
description it seems that all of your user-scripts are being run from the
same application domain as the hosting programm.
If you try to adopt your programm that those scripts are being run in separate
application domains exceptions in your script won't crash the whole programm,
just one single domain will die and invoke an UnhandledException event. That
event could then be taken to put that exception into whatever form or system
you might require.
