I emailed the developer a question and he replied quickly.
Install note: After installing the plugin, replace the SWF file in /plugins/content/BonckoSlideShow with the one that comes with the SlideShowProStandalone version.
Helpful tip: In the Module Parameters section, be sure to enter the Module Title of the module you want to display inside the floater. This isn't totally clear in the instructions. You may assume, as with other modules, that some of the parameters are optional. They are not. If you make a custom module with some code in it and title it Daily_Update, then you must enter the Module Name ("custom"), and the Module Title ("Daily_Update") for the floater to display your content. Hope this helps someone save some time getting it going.
