LIkely not unless the new window location is off screen (-100,-100). Freeze only works on the current window. For FMGo you cannot hide it at all. Sometimes better to just change layouts than to open a new window.
thanks Big Tom !!!
I might be missing something here, but if you don't want to see the new window, why open a new one and then hide it?
Why not Freeze the current window, then if you need to switch layouts for the rest of the script, just do the rest of the script steps without opening a new window? The script runs while you see the original window.
