Further information: when i spam back file button & turn on pause on errors, breaks at point shown in the image.

Maybe one thread is running into this point when another thread has deleted handles.LABELTAGS?

If that's the case, some resolutions could be:

1. add try statement here, to pass when handles.LABELTAGS doesnt exist
2. block buttons while replotting labels (would make switching between files slow when hitting >> button several times.)
3. delay before actually plotting labels

further update: file switch buttons do in fact grey out when switching files, but i think there's a delay.
