The latest v450(.1) release of the Scratch player now removes an ask prompt when the asking script gets stopped. You can stop the ask script (and so now get rid of a pending ask prompt) in either of two ways: 1) use a "stop other scripts in sprite/stage" block (as in this demo) 2) get a clone to ask, then delete the clone (which stops its script) This makes it rather more intuitive to remove an ask box than the somewhat hoop-jumping methods required before... :) (Also, the speech bubble outline is now light blue for an ask bubble, rather than the mid-grey of a normal speech bubble.)
