Bug with WP_CONTENT_URL

I have used Blue Captcha sucessfully on a couple of WP sites so far. In a recent setup, I chose to change the default value of WP_CONTENT_URL from the default of ./wp-content This did not impact all of the other plugins I am using, but Blue Captcha fails to find its ./bg and ./fonts directories. I took a quick look through the code and while WP_CONTENT_URL is referenced at the top of bluecaptcha.php, it appears to be hard-coded as ./wp-content throughout the file and in the other .php modules in the blue-captcha plugin folder. A quick symlink from ./wp-content to my new content folder and it works again, so I am pretty sure that is the problem. I would appreciate it if you could address this, so I don’t have to modify the code myself and end up breaking on the updates. Should be a quick and easy fix for you if I am correct. Thanks for a great plugin! https://wordpress.org/plugins/blue-captcha/
