I am using Corel Draw 2020 and had the same problem that RjMaker with CD 2018 had in Dec - that solution still works for this version of Corel Draw.
But two more problems appeared:
The export does not bring in the layers to Lightburn but rather imports everything into one layer. Does anyone know a fix for this?
The export macro works when Lightburn is not opened and works generally well. If Lightburn is already running the export fails with no error message alerting the user. This is inconvenient but not a killer although was not obvious when I first tried to use the macro.
Thanks for any help!
