Bug - Can't see all the actions available in Interaction table

If the Interaction table is out of the Axure Interface, I can’t see all the actions available. Scroling is not working, so I cant select the last actions like “Wait” for example. See screenshot below.

Sorry. It displays the end of the list on my screen below. I didn’t see it before I post this. That was why I couldn’t scroll.

Anyway, this window has a wired behavior, I find. I already post a note about the fact that there is no border and you have difficulties to see it if you have disabled window shadow on Windows (my case).
