A new release of Eos software is now available. This addresses two potential crashes related to the use of Undo and Curves. Please see the release note posted with the software for additional details.
If you wanted to go back to 1.2 from 1.2.1, just reinstall 1.2. You can edit and save your showfile in 1.2.1 and then load it in 1.2 without any worries. All of the changes in 1.2.1 are in functionality that is independent of the data that is stored in the showfile.
