Bug Fixes

• Fixed a calculation error that stopped deflection results from being produced when a beam rested on spring supports only.
• Fixed the deflection results freezing on a spinning progress indicator for the rest of the session once a calculation had failed once.
• The deflection checks 7.4.1(4) and 7.4.1(5) now state why no deflection could be calculated.
• Fixed an issue with some older files that would not open.
• Stability fixes for rare errors that could leave part of the interface showing results that no longer updated.
