I have purchased the software and find it very cool and was messing about changing the included fxs and saving the changes to the geon file the editor seems to save the geon file but on going to load the changed geon file it's not where I saved it .
G:\Geon_FX_Pro_v1_0b_Win\Effects\100\100.geon = original file
I would change it and save it as
G:\Geon_FX_Pro_v1_0b_Win\Effects\100\100mod.geon but file is not saved here .
Instead it is saved in
C:\Users\username\AppData\Local\Geon_FX_Editor which is not expected as path is shown as above.
I have Win 10 if that helps.
