Unable to select and move labels in MapInfo Pro

Product affected: MapInfo Pro™

Resolution

UPDATED: December 4, 2019
There are two possible workarounds for this issue;
  1. When a particular label cannot be selected, select Control+D on the keyboard to force a redraw. This fixes the problem for a while. The label that previously was not working properly should now be selectable and can be moved. 
  2. There may be an issue with the table.  Try exporting the table to MIF/MID, then re-imported the MIF/MID as a new table.
