I have also found that my text size is reset, and the user interface text size box goes missing, after I have regenerated any thumbnails for an aircraft.
I'm aware that I can get this back by deleting the preferences folder, but that's a bit of a pain as I lose all sorts of settings for my controllers. So my question is - is this text size value stored as a variable in any of the preferences files? It would be so much easier just to be able to set it manually if it gets reset by some other action.
Thanks in advance
