I have two instances of Slideshow and both had problems following upgrade to version 2.2.0:
1. Slideshow expanded to fill whole page width. I fixed this by try different settings - Maximum width, Shrink height when width shrinks, Slideshow's height. I'm not really sure why the settings I've ended up with cured the problem!
2. Slideshow included in a table no longer works. Re-did the page to avoid a table
