Click the green flag to start. Shows a bug in Goto X Y when the costume is blank. See notes for when costume is blank. Use a non-blank costume and it works as expected.
I found that the buttons (Button3) were not placed as I expected so I added the 'places' list to record the values of target place (x,y) and actual place. For example in line 1 target was -180 90 and actual was -41 23 It all seems to come from having an empty costume selected when the move starts. If I add something to the 'Blank' costume it all works.
