Editing attached pdf files
I have attached pdf files to my mind map in MindManager 2020. When I open these from inside the map in A Foxit PDF, I cannot save any changes. It says that file might be read-only, but I have checked the properties and it isn't. I've checked the MindManer help guide, and it should work this way.
Does anybody know how to solve this? Could it be that the local folder is somehow protected and if so, how can I change this?
