Adobe Air windows that don't show up on taskbar (I dont mean UTILITY or LIGHTWEIGHT)

I want to create a new Adobe AIR window from my application. I want the new window to be a normal new window but not to re-size, minimize, or maximize but I also 开发者_如何学Pythondon't want it to show up on the task bar. In other words, I want it to be like a browser's alert window. Look carefully when you look at one of those, the type of window is not a utility window.

As it is stated in the link posted by Cay, there are only three types of windows: normal, utility and lightweight. Normal windows do show up on the taskbar. So if you don't wanna use utility or lightweight, I guess you'd have to live with the taskbar.
