Every now and then I discover something that was under my nose for God knows how long. I had one of these moments the other day while debugging some CORBA code - I thought "wouldn't it be nice if I could tell debugger to stop immediately after it encounters CORBA::Exception derived exception"?

Then I opened exceptions settings in Visual Studio and there it was, staring at me the whole time - the Add button. Just type in the name of the base exception class and you're done.
