There are several compatibility issues between MinDgo v4.1 and Freeplane 1.1.3 that make this version of MinDgo inappropriate for use by Freeplane users.
The most serious of these issues concerns the format of the FONT element in the Freeplane data file. Freeplane appears to be more flexible regarding the structure of this data element than FreeMind. MinDgo can’t handle this difference and may fail to import the file. A fix will involve an update to the apps data mode and is in the works.
If you encounter any Freeplane import failures or other compatibility issues, please let me know.
