The Shift+Enter command is run cell, select cell below, so if you are debugging a cell this is probably not what you want. If you use Ctrl + Enter, that is just run cell and should not move your cell cursor.
This may be what is causing your issue, as jumping to the next cell would also show you your output, misleading you on the cause of your issue. Using Ctrl + Enter in my 5.2 notebook does not move my screen position at all.
