CXTColorPicker does not send No Fill msg

I am trying to capture the event when a user hits the No Fill button on CXTColorPicker control. I have mapped ON_CPN_XT_SELNOFILL message but it crashes my app. My handler never gets called. It seems a bug to me. Any help will be appreciated.

 

Here's the code snippet:-

 

First of all many thanks for your help and input.

I tried the same code above in the codejock colorpicker sample and that crashed again and at the same place. Please find the call stack below.
