Metasequoia 4.2 *.mqo file includes a thumbnail

Be aware that Version 4.2.1 of Metasequoia embeds a thumbnail image in an *.mqo file by default.

This means a large increase in the size of the *.mqo file.

It may also make the *.mqo file incompatible with some programs.

Since version 4.1 was uninstalled when I installed version 4.2.1 I cannot check whether version 4.1 also saved a thumbnail in the *.mqo.

You can disable this feature by clicking File>Configuration>File and unchecking “Embed a thumbnail”.
