Thanks Ajay,
but there is a small tweak in there, if it was a pop up message i.e. of type 'I' then I would have handled it as you said, but its not a pop up! It is a warning message at status bar of type 'W', so handling with that logic is not possible. I hope you got my point 
So how can I handle such messages? *-)
Thanks,
