new windows and using them as a selection tool

Has anyone done anything similar to this and/or knows how to go about
it?

1. The user clicks the field to assign an employee
2. a new window pops up with a search field and selection portal
3. the user types in search term and the portal reacts
4. user clicks button to assign employee
5. the new window closes, then the employee's name is in the field in
the original window.

Questions:
1. how do you prevent them from 'x-ing' out the new window? (I have
a cancel button that i need so that i can run a script that not only
closes the new window but maximizes the original window)

2. am i able to keep track of which field i just clicked on (at the
beginning) so the program knows what field to input the name (at the
end)?


Here is how i was planning to go about it:

1. have a button next to the field that they click which executes the
script to open a new window
2. have them use the search portal as described above, with a button
on each line that executes a script that creates a new variable with
the employee's name
3. in the same script as the one used for step 2, close the new window
and go back to the original field and puts the name in the appropriate
field (hopefully somehow captured at the beginning), then maximize the
original window.

Also, when i set a new variable in a script step as global (i.e. $
$variable instead of $variable), do i have to worry about clearing
that out, or does it disappear when the program closes?

Thanks in advance,
