HI All,

I have a couple of our team members having some challenges with H2K. Usually, our team members model all the geometry and the HVAC first and keep the window inputs for last, as they are time consuming. They usually save the file once they have completed those steps prior to entering windows. That being said, it happened serval times that when hitting the SAVE BUTTON, the software shut down and deleted all the window inputs. has anyone encountered this? would you have an idea of why this happens?

I do some modeling of windows in tree view and finish all of them together in the list view. When I was upgrading glass block and changing their energy star value from 0 to 1, the file was getting crashed. It happened with me for 2 times when I lost the complete file. So I think you should check for glass block. Other than that, I do not see any reason of file crash for now.
