by accident @rastoki pointed out the solution regarding to captcha challenge failed to open in browser

solution:

settings > user interface > window management
in 'show new dialogs:' > select either 'in front of all windows' or 'in front of all windows and focused' will do the trick


this really explained what I noticed and described in the post above quote,

I think I know why Captcha open in browser fails when jd windows is Not in focus but works fine when is it in focus/active/the top most windows.
