When I run some HyperCard piles under Executor/dos; I've very annoying refreshment problems: the screen refreshes only on the way of the mouse pointer or when I move the window. I tried to use the shift-alt-5 menu to change screen updates, but there are no changes. Is there something to do? If no, will this problem be fixed in the near future?
