Wait bar/ Progress bar/GUI

Hi,

I'm trying to use the wait bar in a gui for a matlab program that recognises images. In simple words, a bounding box(rectangle) appears when there is a irregularity.

The bounding box doesnt appear when I have the waitbar as normal or modal:

f = waitbar(0,'Please wait...','WindowStyle','normal');

But the bounding box appears when I use the following command

f = waitbar(0,'Please wait...','WindowStyle','docked');

I would want the wait bar to pop and not be docked. Any suggestions? Recommendations?

Thanks
