Captivate 9 opening a URL glitch/challenge?

I have created a series of interwoven captivate pieces that all play from a web server.

I have set it up as follows training.company.com/training for the main menu.  When you select an item, Caprtivate uses an open URL button that goes one step deeper for instance training.company.com/training/training1.  Captivate carries the extension so in my goto url button on the menu I simple put in training1 and the rest of the link is taken with.

Here is my question/problem.  I now want to create a button from training.company.com/training/training1 that will return me to the original training.company.com/training menu site.  But the only way I can accomplish this is by opening a new browser window. When I try to replace parent captivate sends it to: training.company.com/training/training1/training.company.com/training becuase it carries the extension with?

I have also tried to do it with Javascript using window.location.replace('training.company.com/training'); which yields the same result of :training.company.com/training/training1/training.company.com/training

Any suggestions how to get around this would be appreciated.

Thanks
