Gabriel,
First thing to make sure is that you have the latest patch installed. You can find the MapInfo Pro 16.0.2 Update here:

If you already have installed the patch or you don't see any improvements after installing the patch, I would recommend you to reach out to our technical support (software.support@pb.com). They will help investigate in what circumstances this issue occurs.
