TAdvListBox - unexpected behaviour in search edit

Another case. Take the TAdvListBox Demo:

- Hide insert box
- check "Auto search/filter
- Search/Filter style: "Filter"
- Filter method: "Contains"

type "sw" in search edit --> you see 4 items -- o.k.
press ESC (escape) key --> edit is blank, all items visible --> o.k.

type "sw" again
press TAB once or twice --> focus is on another control
klick in the search edit field again (set focus)
press ESC again --> "sw" remains or sometimes disappears --> still 4 items visible --> not o.k.
from now: everytime you press ESC "sw" is in the search edit. I'ts kind of stored somehow?

The issue was traced & solved. The next update will address this.
