Hide task bar tabs?

[RGould8 at aol.com]

I've got a Revolution application for Windows that I'd like to run 
"invisibly".   So far, I've been semi successful by setting it's properties to "hidden", 
and setting the stack's visibility to "false".

What I'd like to do, however, is make it so that when Revolution does need to 
"pop up" a window, that the Windows task-bar at the bottom of the screen 
doesn't display a the tab for my revolution app.   What's really interesting is 
that my Revolution app has a main stack, and a substack, and when they both 
display, I get 2 tabs listed in the task-bar. (the substack displays an asterick 
next to it's name).   Is there a way to suppress this Windows task-bar display 
update, so that when my Rev app does a "visible of this stack = true", that 
the taskbar at the bottom doesn't change?
