Closing palettes

[Richmond]

I have a palette that is a substack of a multi-card stack (i.e. nothing
screamingly original) called "FLOATER".

On the palette I have a close 'iocn' and when the end-user clicks on it
it execute this script:

on mouseUp
    close stack "FLOATER"
end mouseUp

which it does . . . . . which is all jolly well and fine, BUT . . . it 
also returns the main
multi-card stack to card 1 every time; something I should like to prevent.

???

Pretty Please.

Richmond.
