Another strange thing. If I type: someIdentifier.
I get an automatic auto-complete popup after typing the ‘.’, populated with all the methods or members I could finish with. But as soon as I type one letter, eg .’i’ (to select "isSomething()"), then I get a “Please wait…” and a few seconds of delay! The entire list of possibilities was already presented to me, narrowing it down after I hit another letter should be instant. Something is going wrong.
