Ever since I installed Glyphs 4 I get this message when opening Glyphs 3 – every time, even if I select one, it asks again next time. What is this? How can I remove it? 
Do you want all documents with the “.designspace” file extension to be opened with “com.GeorgSeifert.Glyphs2”, or do you want to continue using “FontGoggles”?
- Use “com.GeorgSeifert.Glyphs2”
- Keep “FontGoggles”
