So you 2 finger click over the sprite and then click anything on the bar outside scratch. It should make the save image as option bar appear but the screen for new tab or extension won't appear. Now, try hovering your mouse over the sprite. This works because scratch thinks that your mouse is down but when you click on a place outside of its mouse detection field and cancel the mouse lock, scratch hasn't noticed the mouse is up and will act accordingly. this only works for mouse detection code that does not use the When this sprite clicked because for some reason that block also has the unsaid feature of a Wait until combined with a mouse down and a not makes this only work if you use a forever block and add if mouse down and touching sprite1 for the detection method.
*WARNING* This will only work if you are using a Chromebook This is a bug with scratch, might get patched
