I'm not sure, but i think "lock screen" only applies to actions inside 
one stack...

Means:

...
lock screen
set the loc of btn 1 to 200,300
...
unlock screen
...

will work, but

...
lock screen
close stack "x"
toplevel "stack y"
...

will not.

Someone correct me please, if i'm wrong.

Yes, they do not empty.

In memory, but you can delete a global with:

delete global yourglobalvar

Hope that helps.
