redndahead thanks for the tip http://drupal.org/node/815948#comment-3048102
Currently the description of Timer delay field is:
"Amount of time in milliseconds between transitions."
I suggest to add something like this to description:
"Set the value to 0 to not rotate the slideshow automatically".
"Set the value to 0 to change Main frame only by clicking on Breakout."
(sorry for my English)
