Click on Xfce-panel task list doesn't return to app w/ opened dialog

view story

http://crunchbang.org – I use Xfce-panel with it's task list plugin. When an aplication opens a dialog and a swith to another window, then I can't return to it.To reproduce it: open gedit, press CONTROL+F to open the "Find" dialog. Now switch to another aplication leaving the Find dialog opened in gedit. Try to return to gedit by clicking on gedit button in the tak list, you can't.I know I could just alt-tab to it but sometimes I'm far from my keyboard. Plus this should work fine to begin with.Does anyone know how could I solve this problem without ditching Xfce-panel? (HowTos)
