The window resulting from using the [a] command allows for scrolling despite that there are only two skills that can be used.
Okay, so use the [a] command. It brings up a list of useable skills, right? There should only be two of them.
Despite this, the window still allows the use of the [+] and[*] commands, and using them allows you to scroll through blank pages. Furthermore, if there are no valid skill selections on the current page, the list of available commands at the bottom of the window starts to misbehave.
