If I have a reasonably long document in Acrobat Reader and I do a search, when I type the first letter in the search field it counts the number of occurrences of that letter in the document, which can take several minutes (e.g. there were over 10,000 ds in the document I was searching), then the number of occurrences of the first two letters, etc. Is this supposed to happen? It is very frustrating!
I have got round it by typing the whole search phrase elsewhere and then pasting it into the search field, but that's not idea.
