great update, but the find as you type window appears over DOpus on any charactor. DOpus has special charactors (>, ?, space, #, =, :, @) that perform different functions. Can you not bring up the filter box when these chars are initially pressed?
The chars are detailed here: http://www.gpsoft.com.au/help/opus10/default.htm#!Documents/Findasyoutype_Field.htm
