Here is the source code in LV2019 SP1, can anyone check in LV2020 please?
We have two ears and one mouth so that we can listen twice as much as we speak.
No Crash on LabVIEW 64Bit 2020; have not yet installed SP1. Crtl+S and Save from file menu both don't crash.
Win10 64 bit
So set the default value on a Map with a class causes LabVIEW to crash when attempting to save? Yes, causes LabVIEW 2019 SP1f3 to crash. LabVIEW 2020 SP1 worked just fine.
