Alex,
Actually this is consistent behavior because your context is switching.
"This" always refers to the object that has the focus. If you have a stack
named "stack one" and another named "stack two", and you have a button on
"stack one" that says:
on mouseUp
go to first card of stack "stack two" as toplevel
end mouseUp
the current stack with the stack with the focus ("this stack") *before* the
"go to" command is "stack one", but once you opened another stack, it now
has the focus, and so "this stack" is looking at "stack two". If you want to
change the focus, you can use "set the defaultStack to <stackDescriptor>" or
do what you did, which is specifically address a stack by name when you
close it.
BTW: stacks open as topLevel automatically (unless you specify otherwise),
and will open to the first card as well, so you only need: go to stack
"stack two".
So if you want to close one stack and open another, you can do any of the
following:
on mouseUp
go to stack "stack two"
set the defaultStack to "stack one"
close this stack
end mouseUp
on mouseUp
go to stack "stack two"
close stack "stack one"
end mouseUp
on mouseUp
put the short name of this stack into tStack
go to stack "stack two"
close stack tStack
end mouseUp
And I'm sure there are a bunch more ways to do this. But you get the idea.
Hope "this" helps,
