Hi folks, got this idea about creating a window that pops-up in an animated way like the yahoo messanger notification panes that pops up gradually from the bottom right conner of the computer screen when one of your chat friends comes online.
I am having problems trying to make the pop-up window show from behind the task bar.
Any ideas about this entire application will be welcome. Thanks
