I have opened a Excel, text, CSV or other file in MapInfo Pro and created points.
When I zoom in and out the layer disappears.
Solution
this is usually caused by have blank/empty rows in the source file, which in MapInfo (which doesn't allow for null/empty numbers) they are converted to zeros. this means you have created points at coordinate 0,0.
Simply open the browser and sort by the X/Easting and Y/Northing fields to check for 0 values. As this is a non-native file, you will need to open the source Excel/Text file and edit it in the 3rd party program to delete the null row, and then re-create the points in MapInfo.
