I play poker online. When a decision is required, the relevant window activates and brings itself in front of all other windows, so that I can act in time. However, I can pay attention to all opened poker tables on my own, and thus, this feature has little to offer me. It can get extremely annoying though, for example when I start typing something into an email but suddenly get switched mid-air to the poker table chat box.
Fortunately, some of the more advanced poker software has an option to turn off this aggressive behavior. However, others don't. Is there any kind of system tweak or tool that can block software from activating its windows? I want to be in total control regarding what window is active, at least for my poker playing sessions.
I use Windows XP.
