I get it every time with V38 after closing the software. It doesn’t appear to affect anything though, maybe some extra lag closing the software.
V38 has problems. I’ve been working with bobcad support to fix or work around the ones keeping me from getting work done. One guy let slip that V39 is in the works to be released this fall. I would encourage bobcad to stop the endless annual release cycle and concentrate on long term releases. Release a stable version of bobcad, patch it as bugs are found and give customers a sense of security that the software will be maintained and supported for the foreseeable future. Say, a 5-year release cycle. I upgraded to V38 after 8 years of using V30. V38 has some of the same issues V30 had, they NEVER got fixed. The new UI looks modern, and we got new toolpaths by upgrading from mill pro to mill premium, but I really think V30 was more stable and easier to use. It is also very frustrating calling support for help and being told that your version is too old and no longer supported, but after you upgrade the same problem is still there. After spending thousands of dollars on a piece software I think I deserve to have it work correctly as advertised.
