unpleasant behaviour of dialog windows

[askoff]

BSPlayer (non pro) 1.22 build 817 from BSPlayer website. Windows XP.
Always on top mode is on in BSPlayer.
I was using "Color controls" settings in BSPlayer while the movie was playing. Then I accidentaly clicked other window (in this case explorer window) and the Color controls windows went behind the movie window. Now I couldn't acces any window because the close button in Color controls was behind the movie window and other BSplayer windows wasn't responding. Alt + F4 solved the problem, but I think that situation should be fixed.
Also "about" window suffers from same problem.
