Slide show by StefanBoonstra – Unable to set width ver 2.2.21

Hello, I have been working on this for days and have read through the forums. It appears that quite a few users have the same issue but the resolution has scratching my head.

I am running the Slideshow Plugin by StefanBoonstra and like the plugin except for the width settings that do not appear to work. I am running the most current version 2.2.21

My theme is a basic theme that has a width of 1200px. My images uploaded are 900px width. But my slide show will only display 584px no matter what I do. I have tried to reset the slide show properties height to 600 in hopes that the ratio would increase the width but it only stretches the image vertically. I have the width set to 0 because no matter what I set it to it has no effect on the width but it says that 0 will be the maximum width. I have tried to reset the image behavior and no setting seems to make any difference. I looked in the General Settings under Custom Styles but there is no reference to the image width. Is there any code or change I can make so that I can get the maximum width out of my images in the slideshows?
