Hmm, thats when pressing C for coordinates yes? Does it give the same behavior in NVDA? What operating system and hardware are you using?
To create animations create or load the desired frame images into brushtone, pressing tab can allow you to toggle between them. Then press F1 for the canvas menu and select "save image". Enter a name and select "gif" as the format. Brushtone will then take all the images currently loaded in order and save them as a gif animation. Note that the images should be the same size, and the number of colors in the images will be automatically reduced to 255, so some detail may be lost in high quality images. Also note that gifs will not save with transparency.
