I'm using a Listbox filled by a SQL statement (works fine).

Issues:

1. However, I cannot get the number of lines in the listbox to be greater than the default (4 lines) no matter how large I specify.
2. If I set the listbox to Multiple select, it does allow multiple select but if I go back in to the question's configuration it is set back to Single (bug)
3. Is there a way that multiple select can use click on / click off (more intuitive) instead of CTRL-Click for multiple select?
