The searches in the File/Open and File/Save dialogs seems to be taking 10 times as long as they did a month ago, although most other functions of the program seem to be no different and the folder sizes haven’t grown much. The View in which the search result is to be presented doesn’t seem to make any difference to the sluggishness of the searches.
The impression given is either that the folders are no longer being indexed, or that indexes exist but are no longer being searched, or that searches were being saved for redisplay but are no longer being saved.
Have I inadvertently switched an option that controls these searches?
