Today, I started Aris Express for the first time in a few weeks. It was automagically updated to version 2. I am not sure what all the changes are, but the new whiteboard and BPMN diagram seem very useful. Check out the software at: http://www.ariscommunity.com/aris-express.
More information about the new features of version 2.0 can be found here.
Earlier this week I was struggling with an XSLT transformation. Usually it sort of works and requires some tweaking. But now I could not get it to work at all. I was doing the transformation from within a .Net control.
