Just released a new version of XSRDice. Basic rolling and most of the common use cases of standard tests should now be working. I still need to implement Opposed and Extended Tests, but they're coming soon.

The program is open source and you can get the source code from the Bitbucket Repository.
I really want to get this silly little dice roller app finished and out of the way so I can concentrate on doing the character generator I've been planning out.
Any feedback is always appreciated.
