code injection - change behaviour of windows program

I need an application for windows (should work with xp and vista), that changes the behavior of a certain existing program. I am just the end user of this program and obviously don't have any source code. A poker gaming application runs a multiple number of overlapping windows, one for each playing table. Each time action in one of these windows is required it will pop up to the front and prompt for user input. The problem is: A window will pop up to the front without waiting for the user to finish action on a previous window. This leads to annoying, nasty misclicks. solution needed: Your app should recognize and hook into the gaming windows. Their behaviour should be changed in such a way that activating and popping up to the front is suppressed unless there is no other window currently waiting for user input. As poker is concerned, user input means pressing a 'fold' , 'call' or 'raise' button. *Suppressed windows should be put in a queue, wait for an active windows to finish with user input and be activated immediatly afterwards. *Your app should work smoothly for at least as many as 8 windows simultaneously. *Your app should recognize newly opened windows and allow existing ones to be closed smoothly. *The program in question can be downloaded for free from [login to view URL] and [login to view URL] after registering a free account. *[login to view URL] and [login to view URL] provide the same gaming software clients under a different name. Your application should work on both clients interchangeably (it is impossible to run both clients at the same time). *Before posting a bid I'd like you to have a look at the software and see if you feel comfortable with the project. *I am willing to spend $200 for this project *You will need a fast, stable Internet connection for testing purposes.
