Changing the default width of a highlight box in Captivate 5.5

Hello,

I have a question about setting the default width and height settings of a Highlight box in Captivate 5.5. I know how to adjust those settings in an individual instance -- I select the highlight box, open the Windows menu, choose Properties, and then adjust those settings under Transform (where I can change X, Y, W, and H). What I don't know how to do is accomplish that globally, before I make a recording. I know how to access the Object Style Manager, but no matter how I access that, I never see the Highlight box on the list of styles I can edit, and I don't see the Transform settings in the Object Style Manager, so even assuming the Highlight box was on the list of styles, I don't see how I can edit the W and H settings.

The default setting of a Highlight box is 34 by 20, which is not wide enough for the menu options I typically click on and want to demo.

Thanks very much in advance for any help. I apologize if I am missing something obvious....
