What sort order do you use? If it is not (default) 'Filename, Natural sort' you're hit by folder re-sort (assuming files come in 'natural order'). You may try to turn off the Preferences - File Handling - (Sorting and Filtering group) - Scroll to selected image while filtering/metadata being read setting.
Also, you may turn off Folder re-read via Preferences - File Handling - (File browsing group) - Check for folder updates each (set it to zero).
To re-read folder use Menu - File - Reload - Reload current folder (Windows: Ctrl-Shift-F4/Mac: Cmd-Shift-F4 with default shortcuts set)
