Hi timesnaps ... I'll investigate the caption issue, I wasn't aware of a problem but I'll check it out.
As for the increasing the fullscreen image dimensions, there's actually something brand new in 1.9.1 that allows you adjust that size. I don't think I've mentioned it yet, but it is in the release.
First, download Soundslides Plus 1.9.1:

Mac OS X:
Then you'll need to enable two Advanced parameters then re-output your project.
1. Go to advanced parameters (Modify > Advanced parameters), then click ADD and add the two parameters below.
Don't go nuts with these sizes. I personally think 1280 wide by 900 high is pretty much my personal limit. Beyond that, and you're pushing the Flash Player on your audience's computer. Also, your source image files will need to be at least as large as your new max fullscreen size.
2. Then, go to Output sizes (Modify > Output Sizes), and click "Apply"
3. That's it, hit TEST and check out big fullscreen.
