If I select 'relative' hyperlink types in Preferences the hyperlink remains 'absolute'.
For example: file:/C:/Users/xxxxxx/Google%20Drive/WORK/SID/Mindmaps/Riunioni%20SID.mm#ID_1855626460
This is a great problem when I use the same file with hyperlinks in different PC (home, work,...)
More detail... the problem exists when you use 'Set link anchor' and then 'Make link to anchor'.
Otherwise it works fine.
Changing the preferences should not change existing links, they apply only to the links you create in the future.
Do you still see any bug if you consider that?
Obviously, the problem is that with preferences 'relative hyperlink' the links remain absolute using 'Set link anchor' and then 'Make link to anchor'. Thanks...
Fixed in Version 1.5.17_01 (preview version).
