I was gonna sell this information but decided I would just give it away instead. Now it is actually very easy to trick Xrumer into breaking your own captchas. So simple in fact that I am sure that many people didn't even think of doing this.
Since the captcha breaking is done in a browser Imacros & UBot can both be coded to work with the script. I am a complete newb with php, so if the script can be done better and you want to be the one to fix & share please PM me.
The instructions are posted on my site:

Have fun.
