How do you keep the Taskbar up

Hi.

Using QNX RTP…

This is a stupid question. But, how do you keep the taskbar up and in front
of everything?
Whenever I run an app and maximize it, I always loose the taskbar.

I can get the auto collapse to work (when there are no apps maximized), but
when an app is maximized the taskbar does not come up when I move the mouse
to the bottom of the screen.

Thanks

Augie
